Multiple or Repeated Login Screens or Password Prompts


If you are being asked multiple times to log in to your email account, here are some possible fixes.

Google 2-step authentication

If you are using Google 2-step authentication, you may have entered different passwords generated at different times for incoming and outgoing servers.  

To correct this, refer to the Setting up GOOGLE / GMAIL Email Accounts article.

Reset your passwords

Try removing ALL of the passwords from your Password Manager.


  1. From the menu bar, open the Postbox menu and select Preferences > Security > Passwords.
  2. Click on Saved Passwords.
  3. Click Remove All.


  1. Open the Tools menu and select Options > Security > Passwords.
  2. Click on Saved Passwords.
  3. Click Remove All.

The next time you check for messages, Postbox will ask for the updated password.

Third-party applications

Third-party applications could be blocking login attempts. Try temporarily disabling these applications to see if the issue clears up for you:

  • Virus Checkers can sometimes prevent the password from being saved to disk. Disable the virus checker, enter your password in Postbox, close Postbox, then re-enable your virus checker.
  • Backup Programs can sometimes repeatedly backup the old password file, which contains an older password.
  • Disk Cleaners can sometimes alter file permissions on disk. Disable these programs and repair your permissions on disk.


If you are using Gmail, you could be running into a Google "CAPTCHA" issue.

To correct this, try resetting your CAPTCHA.
