If you used the thunderbird export feature, it automatically deletes passwords from the exported profile. If you copy the profile using the windows file manager, they're kept. If the old computer is still available, click to settings>privacy&security and then click showpasswords .

Thank @david I guess my reply reply was deleted. I'll try again.

I copied the entire contents of the ///profiles/name/*.* over to new machine. Then when that just copied the emails over, required for each of 34 email accounts,. Email works, but can't login get anything new,

I explained that I know where the Password manager is via Tbird, but it did not copy all the . I also have 34 email accounts, each with specific settings; such as IMAP, or POP, and other prefs for each one.

I expected that the passwords and prefs would follow same logic as copying the emails over. Do I have to manually enter all the prefs and redo all passwords?

Puzzling. For the past few years, my suggested steps have worked for many. Important that thunderbird not be running when the appdata\roaming\thunderbird folder is copied. The only accounts where I have to reset is where there are app passwords. If possible, I suggest starting over. The steps I use are these:

here is the info in brief steps:

1. ensure thunderbird is NOT running on old machine
2. enter %appdata% in search window on task bar and press Enter key
3. this should open windows file explorer in Appdata\roaming folder
4. highlight the Thunderbird folder and copy to external media
5. ensure thunderbird is installed on second computer, and NOT running
6. enter %appdata% in search window on task bar and press Enter key
7. you should be in Appdata\roaming folder , copy&paste the exported Thunderbird folder there. This may prompt to overwrite an existing folder of same name. allow it

#   start thunderbird and all should be there

@redacted,

This is resolved?
