Hi,
For web clients I have a 2 factor/form authentication. I use a web 2 factor(google authenticator) .
I would like to add a 2 factor authentication for the e-mail client(thunderbird, android phone etc).
Can someone advise(also appreciate a tutorial for it)

Edit: Is it possible to have a two  factor authentication for standard IMAP/SMTP connections?
