I have added my Yahoo Mail account to Gmail app on my Android phone (Samsung Galaxy Note 3, latest Gmail version)

However, ~5 times out of 6, the app fails to log in to Yahoo (the username/pwd and other settings are clearly correct since it does succeed in connecting once in a while).

Server is android.smtp.mail.yahoo.com, port 465. SSL/TLS security

Error is "Username or password is incorrect".

What could be causing this and what can I do to fix?

I encountered the same issue. I didn't find a solution yet, but I'd like share my opinion on the possible cause of this issue.

After I re-try the sign-in, the sign-in page shows an error indicating redirection loop or proxy loop error.

Sometimes, I get error message saying that I'm trying to login from an unexpected country, and I have to verify the log-in with a SMS message.

Some other cases, if I login the www.yahoo.com with the browser, with password and CAPTCHA, on the same connection, I re-try the login in gmail app, it works.

Most of the time, in the gmail app, when I re-try the log-in, I just get a dumb error message that leaves no clue.

My theory is that the yahoo server does a lousy job when it tries to balance between the user convenience and security. The server is too sensitive to "suspicious" login attempt, and didn't have a better way to offer CAPTCHA validation with the gmail login.

Remove Yahoo account from device and manually add it later.
In Manual Setup, Port 443 will be assigned and Server is set-up with android.smtp.mail.yahoo.com and Security type as SSL/TLS

Gmail used to logged in to Yahoo using regular IMAP, but recently it was changed to Yahoo authentication which failed frequently.

The solution is to find a copy of the Gmail 5.1 APK, install it, and setup your Yahoo mail. This version allows you to setup regular Yahoo IMAP.

After that, you can upgrade to a more recent Gmail version.

  • You can just add it manually as IMAP instead to get the same effect. – binki Oct 4 '17 at 19:32
  • No point in manually installing old APKs and stuff from iffy sources. – binki Oct 4 '17 at 19:48
