It keeps asking for my password but won't accept the usual password.

Question

When I try to access my account I get the following error message: "Sending of password did not succeed. Mail server pop.gmail.com responded: Username and password not accepted." However, when I look up the account information the username and password I see are the same ones I have been using. How can I clear this up? I tried setting up a new account but it didn't work. Thanks!

If you changed your password in gmail webmail account, then you will need to remove and re-enter the saved password in Thunderbird.
re: Error message 'Username and password not accepted'
I have known a similar issue occur after an update.
I've also experienced a server request to loggon to webmail account cuase this, in which case logon to webmail and everything works ok afterwards.
That error message could mean the username and password are incorrect or it may not be correct for the chosen settings - meaning the settings are wrong.
Note: Username = full email address.
So try this:
if the password was remembered, remove it.
'Tools' > 'Options' > 'Security' > 'Passwords' tab
click on 'Saved passwords'
click on 'show passwords'
If Thunderbird password manager was instructed to remember passwords, they will show up in the list. There will be be two, one called mailbox and the other smtp. highlight both and click on 'Remove' then click on 'Close' then click on OK to save changes to Options.
Close Thunderbird and wait a few moments for background processes to finalise.
Restart Thunderbird.
On startup it should prompt for a password.
enter the password,
make sure you select the checkbox for Password Manager to remember the password
click on OK.
