I am getting this error when I try to send mail using the JavaMail API:
javax.mail.AuthenticationFailedException: 535-5.7.8 Username and Password not accepted
How can I fix this?
Sorry for coming late to Party.These could be the problem in your task if you are using Gmail Server.
Two Step Verification should be turned off.
Allow Less Secure App(should be turned on).
Please Check Your UserName and Password.
Check the code(which was my Problem), Above three You can change form google help center and by Yourself last one My Experience I can Share with You.
You need to Authenticate the Mail server before Communicating the message because it is Challenge Response System By which You are Communicating through the mail.I am sharing code snippets file you can refer not able to format my code by ctrl+K.
This worked for me:
Login to the gmail account you are sending mail from
Go to Manage your Google Account -> Security -> Less secure app access -> Turn on access (not recommended)
or
Access the URL:
https://www.google.com/settings/security/lesssecureapps
Turn "Allow less secure apps: OFF" to "Allow less secure apps: ON"
Update:
Google stopped supporting "Less Secure Apps" as of May 30th, 2022.
One of the alternatives to solve this problem is to use 2-Step Verification and generate app password:
Google Account -> Security -> 2-Step Verification -> Input password as asked -> Turn ON (you could use SMS to get Gmail code to activate 2-Step Verification)
Google Account -> Security -> App password -> Input password as asked -> Select the app and device... -> e.g. Other(Custom name) -> Input app name e.g. MyApp -> Generate
Copy a 16-character password
Use a 16-character password with Gmail username in your application
Google support link here.
Update since June 2022:
Google closed the "Less secure app access",
but opened another option called "App Passwords":
"When you use 2-Step Verification, some less secure apps or devices may be blocked from accessing your Google Account. App Passwords are a way to let the blocked app or device access your Google Account." (see docs).
Follow this answer to set up App Passwords
Hint: when using Jenkins Email Extension Plugin, emailext (which does not permit tokens like Google's App Passwords, still requiring logins), just use App Password as the password, and supply any string as login, e.g. your Gmail address login.
OLD ANSWER , not relevant anymore
Step 1: Log into your gmail account
Step 2: Click Settings
Step 3: Click the Accounts and Import Tab > Other Google Account Settings
Step 4: Click Security
Scroll to the bottom of the page Under Less secure app access, click on Turn on access
Step 5: Set Allow less secure apps to ON
First of all make sure that all properties should be defined as follows:-
mail.smtp.host=smtp.gmail.com,
mail.smtp.port=25,
mail.smtp.auth=true
mail.smtp.starttls.enable=true
Now,make sure that two step verification is off
Allow less secure app (ON) follow this link :-
https://myaccount.google.com/lesssecureapps
Also, check your username and password is correct or not.
It works for me, you must configure your Gmail account with the below steps:
In the security section:
You need to Change "Allow less secure apps: OFF" to "Allow less secure apps: ON"
Log on gmail account, in Account ->
click Security -> turn off 2-step verification and turn on "Less secure app access"
May be because of things above, hope help you
I have the same error but when I run the app from the terminal, it goes away. My email configuration is provided:
spring.mail.host=smtp.googlemail.com
spring.mail.username=weddingcard9999#gmail.com
spring.mail.password=Weddingcard.1
spring.mail.port=587
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.required=true
Follow the steps:
Disable antivirus
Allow Less Secure App On
Two Step Verification should be turned off.
1.Allow Less Secure App(should be turned on).
2.Check Gmail Username and Password..
public static void main(String[] args) {
final String username = "YourMailId";
final String password = "password";
Properties prop = new Properties();
prop.put("mail.smtp.host", "smtp.gmail.com");
prop.put("mail.smtp.port", "587");
prop.put("mail.smtp.auth", "true");
prop.put("mail.smtp.starttls.enable", "true"); //TLS
Session session = Session.getInstance(prop,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("Tarunsunny143#gmail.com"));
message.setRecipients(
Message.RecipientType.TO,
InternetAddress.parse("balachandralucky2#gmail.com, to_username_b#yahoo.com")
);
message.setSubject("Testing Gmail TLS");
message.setText("Dear Mail Crawler,"
+ "\n\n Please do not spam my email!");
Transport.send(message);
System.out.println("Done");
} catch (MessagingException e) {
e.printStackTrace();
}
}
}
Please turn on by clicking the toggle button inside the google security panel.
Then it will allow less secured app also.
Change the settings in Google like this:
You probably got this error because the username and password of the from mail id is not matching. Please recheck your password and mail-id (username). It could be a typo.
In some cases, Gmail prevents logging in through external applications or programs which are not authorised.
Also login to your gmail account to check if gmail has prevented logging in to your account via your Java Mail API program.
If nothing works, you could try some other SMTP server (like yahoo, yandex).
For me works change the property "mail.host" recomended for #Heisenberg.
At documentation says to use "smtp.gmail.com" but works only I use "smtp.googlemail.com".
PS: My Allow Less Secure App configuration was already On
I had this issue while setting up my Jenkins and I resolved it without turning off my Two-Step Verification on my email account security.
This error in my case was because Two-Step Verification was enabled in my email, so I needed to add an app password to generate a password that will give Jenkins access to my mail in order to send emails on my behalf.
STEP 1: Click settings on your email account, select the "Account and Import" tab and in the change account settings, select "Other Google accounts settings"
STEP 2: In the settings screen that opens, select "Security" on the left-hand side, and under Signing in to Google, click "App passwords"
STEP 3: In the add passwords section, click the select app, and select "Mail"
STEP 4: Still in the add passwords, click on the select device and choose "Other (Custome name)".
And in the field that will show, enter a custom name for the app you are creating a password for and click the generate button.
FINALLY: Copy the generated password and use it as your email password while setting up email sending on Jenkins or any other app you are setting it up on.
I just hope this helps someone, give me a vote if it does, Thanks...
Google stopped supporting "Less Secure Apps" a time ago.
I used 2-Step Verification to generate app password and it worked for me:
Go to your Google Account -> Security -> 2-Step Verification
Then follow the steps to turn on
After that, go to your Google Account -> Security -> App passwords -> Select the app and device... -> e.g. Other(Custom name) -> Input app name e.g. Linux Computer -> Generate
Then copy the 16 character password shown in the screen and place it in the your applications config:
spring.mail.host=smtp.gmail.com
spring.mail.port=587
spring.mail.username=myappemailhere#gmail.com
spring.mail.password=mygeneratedpasswordhere
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.enable=true
A couple of answers have mentioned the Less Secure App setting which google stopped supporting in May 2022. Just wanted to clarify that the May 2022 date concerns gmail accounts. If you use Google Workspace for your email, you can still access and enable the Less Secure App Access setting then proceed to use smtp.gmail.com via port 465 or 587.
The help text accompanying the setting says "Important: This deadline does not apply to Google Workspace or Google Cloud Identity customers. The enforcement date for these customers will be announced on the Workspace blog at a later date".

I am receiving this error when attempting to use javax.mail API to send emails over my GMail account. I attempted to check my settings to verify it allows less secure apps to use my GMail account but the Google website says
To help keep your account secure, from May 30, 2022, Google no longer supports the use of third-party apps or devices which ask you to sign in to your Google Account using only your username and password.
Does anyone know where I can find a current guide on how to build hooks to send/receive mail messages with my GMail account that gets around these new requirements?
Access the page with your Gmail/Google Account -> https://myaccount.google.com/security
In the Signing in to Google section, enable the 2-Step Verification
After enabling 2-Step Verification, return to Signing in to Google section
Click on App passwords
Select app as Mail and select device as Other - choose a name
Done! Copy the password and use it with the username account
Google is removing the access to gmail for "Less secure apps" starting the 1st of April (Gmail notification).
That probably means that we won't be able to use javax mail with a gmail account anymore. Are there any workarounds to this?
If you want to keep using imaplib then The easiest fix for the depiction of less secure apps is to switch to using an apps password.
Another option would be to swtich to using Xoauth2 javax mail appears to support that Oauth2
Properties props = new Properties();
props.put("mail.imap.ssl.enable", "true"); // required for Gmail
props.put("mail.imap.auth.mechanisms", "XOAUTH2");
Session session = Session.getInstance(props);
Store store = session.getStore("imap");
store.connect("imap.gmail.com", username, oauth2_access_token);
How to create a Apps Password for connecting to Google's SMTP server.
evening,
i'm trying to do my own email client and then error came.
im using javax.mail library
i did try several methods for sending, most of them crash on sad places. anyway, one method i consider with potential is fine until end when message pops up:
m02 error-2: javax.mail.AuthenticationFailedException: 535 5.7.8 Error: authentication failed: Your message looks like spam. You need to use web for sending or prove you are not a robot using the following link http://ya.cc/[deleted] where [deleted] is originally few letters string.
i saw with gmail, you need to set something in settings to be able to use your own client, i expected this would be similar case but i couldn't find any settings about it in yandex mailbox settings.
another point, smtp address i have found at some forum so i presume it is possible to use own client
properties i set:
properties.put("mail.smtp.host", host);
properties.put("mail.smtp.socketFactory.port", port_ssl);
properties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
properties.put("mail.smtp.auth", "true");
properties.put("mail.smtp.port", port_ssl);
where
private String host = "smtp.yandex.com";
private String port_ssl = "465";
other code, im using classic way: Session for Authenticator, then Message and Transport.send. anyway, i think problem is with properties or mailbox settins? i just cant think of where.
question: how can i fix it so i can send an email with my client?
note: reason for using yandex is thanks to simple sign up since i dont have phone number and gmail requires one. if you know about other email service where own client should work & no need for phone that is also nice alternative answer
As an alternative answer, you could try the service https://protonmail.com, it should not require phone number and it can be reachable by SMTP clients using these settings https://mailsettings.co/protonmail-smtp-server-settings
I was testing the following scenario. Sign in with GitKit and use Facebook as the provider.
All works well, but and the token cookie contains a.o.: "provider_id":"facebook.com","verified":false
Note that verified is false, albeit Facebook emails are verified by Facebook. I understand if GitKit might not want to hard code this assumption, but..
If we then send the user a verification email from our server using getEmailVerificationLink(gitkitUser.getEmail()) again all goes well.
(link is .../signin.html?mode=verifyEmail&oobCode=sFKXzFsKQ4ckr4A-HtofNPkRq_A&apb.cs=1)
The user sees "Success! Your email address has been verified."
But when then redirected to our server the token cookie still says "verified:false"!
My question is if this is the expected behavior?
Because if it is then I don't get it and I would very much appreciate some clarification.
Note, if I sign in with a simple password account, then the token cookie does give "verified:true" after the user followed the getEmailVerificationLink().
It sounds like a bug for social login account. The verified flag should be true after the verification. I will update here once we confirm the root cause.
I have a (java) web-application, and i have enabled NTLM Authentication.
When the logon prompt is presented by the browser in our (windows) intranet environment.
The behavior i see is:
NTLM prompt does not seem to be doing any authentication at all, i am able to type any random string in userid prompt and it allows the user to proceed into the application. The prompt never fails the user.
So, what do i need to check at the server end to find if authentication succeeded or not?
The idea behind NTLM auth is that the logged on user can proceed with connection without explicitly entering his username and password again. So whatever your application asks you is irrelevant (as you can see it yourself) and instead your system credentials are used.
NTLM authentication has been broken for a number of years -- NTLM 2 shipped with NT 4, so hopefully people have moved on by now. If you want to use Active Directory login information, you should use Kerberos instead.
