Getting 'Username and password not accepted. ' initially yesterday am but cleared up with no changes in the pm but back to same problem after working till about 9am today..... Is this a TB problem or something changed either in TB or at my end? I see this response from a previous similar problem but need more info to even start to check this...see below! “If you viewed the password in Saved Passwords, it indicates you're using 'normal password' authentication instead of the preferred OAuth2. First, check that cookies are enabled in TB Options/Privacy or Privacy & Security (TB 78), set the authentication to OAuth2 in Server Settings for the incoming and also in Outgoing Server (SMTP), then delete the passwords in Saved Passwords, restart TB, enter the current working account password in the OAuth browser window when prompted. “ OK, where and how to I view 'saved passwords' and why would I suddenly have to change anything after years of no problems? Running win 7 and TB 6.9.1 ...there is no such option as OAuth2 in the authentication method in server settings in Account settings (gives 'encrypted, kerberos, ktml) is set at 'normal'! Is there a site to go to that would indicate if / when TB is having a problem at their end so we dont spend hours trying to solve a thing that is NOT our problem?
