I am unable to add my email account in Mailbird/ "Authentication failed" message

  • Make sure user name/password are correct: try to log in to your webmail with these credentials

  • Make sure your antivirus/firewall software does not block Mailbird: disable it and try again

  • Gmail users: try to switch from oAuth authentication to Username & Password and enable less secure apps. If you use 2-step authentication this should be the other way around, switch from user name and password to ouath

  • Non Gmail users: make sure that 2 steps authentication is turned off, or if it’s on, generate an app specific password

  • Yahoo users: please see: https://support.getmailbird.com/hc/en-us/articles/227316228
  • iCloud users: please create an app-specific password for Mailbird. Please check out this article on how to do it: https://support.apple.com/en-us/HT204397
  • If nothing of the above works, please log into your web mail, change your password in there and try to add your account in Mailbird after.

If everything above does not work, please submit a ticket to our Support
