The IMAP Login failed error

Why am I seeing this error?

You’ll see this error when your email client attempts to connect to the Proton Mail Bridge app using the IMAP protocol, but you’re not signed in to the app. This can happen for two reasons:

  • You signed out of the Bridge app manually by clicking on the Sign Out button
  • You were automatically signed out due to a technical problem

How do I fix the issue?

To fix the problem, simply click Sign in on the Proton Mail Bridge app. 

Click the Sign in button

Your email client may now ask you to enter your IMAP password. You can find this in the Bridge app once you’ve signed in, under Mailbox detailsIMAPPassword

Find your IMAP password

The problem should now be resolved. If you need further assistance, please contact our customer support
