In your Thunderbird email you can save your each account passwords, so no need to re-enter them when you check for new email. A user can view them as well as eliminate the ones they don’t want to use anymore.
The best part is if you share a PC, and do not want share stored passwords with the master password feature, then Thunderbird will allow you to enter a master password in order to see as well as use the passwords you’ve said Thunderbird to remember. If you have a set master password, then you’ll only require type it once per session.

Step 1: From the top of the Thunderbird window-> either click the Tools menu or simply press Alt + T -> choose “Options”
Step 2: Click on the Application menu -> select Options
Step 3: Choose the Security panel
Step 4: Select the tab Passwords
Step 5: From the opened window check option “Use a master password”.
Step 6: At the Change Master Password dialog select the strong password that is the combination of capital letter, digits, non-alphanumeric character, like: $@ # % & ^ * ( ) etc.
