Issues with IMAP after 2FA enabling
-
Hello,
I seem to have some issues with IMAP and Vivaldi mail. I use it in 3 places - with my phone's Gmail app, with the desktop Mail client that comes with Win11, and with the IMAP client within Vivaldi (latest snapshot).
Vivaldi's Mail client throws a variety of errors, from server timeouts, to not recognizing my password and network connection loss, socket connection etc. Tried using Oauth as well as my password.
I've put Windows Hello as well as an authenticator app as backup in 2FA settings.
What should happen is opening of a popup to require me to use Windows Hello, or the authenticator code, I assume. I think I got that to work, somehow, once, and then back to failure.
Interestingly enough, creating an app password and using that instead seems to work. Webmail works normally, it's just IMAP that has issues.
Thanks!
Edit: just as I was typing this, the Vivaldi Mail went back to Verified. However, when I tried to enter my password in Windows' Mail, which was still not working, it "crashed" the IMAP on Vivaldi Mail too, which again errored out with some socket failure.
I assume this is not normal behavior, you should be able to have multiple clients connected through IMAP? -
Same here: webmail is working fine; the mail client within Vivaldi is working, but Thunderbird (IMAP) does not.
It stopped working after 2FA was introduced.
I am using:
imap.vivaldi.net:993 (TLS/SSL normal password) and my full email address ([email protected]) -
@6shooter Did a bit more digging.
Looks like some IMAP clients don't have the capability to open that 2FA popup.

If you have 2FA on Gmail, the mail client "delegates" that 2FA prompt to your phone, for example. But Vivaldi wants to open it on, let's say, the desktop PC, and the Mail (or Thunderbird) app does not know how to do it so you get stuck.
The solution in the article is the app password which I already found to be working in the OP, but what I didn't know was that it's actually secure and working just for one app you need it to, not everywhere, so it's not bypassing 2FA as it looks at first sight.
I assume that it would take for TB or Mail, or Outlook etc. to add the capability to open the popup.
Maybe a Vivaldi Mail dev can confirm after testing with these apps?
