There is no password caching with Thunderbird. If you want to avoid typing the password again and again you can tell Thunderbird to remember the password (or the OAuth2 authentication token respectively).

Ok, thank you.

Do you know when this behaviour changed? A link to release notes? I never had in over 15 years to type passwords again and again...

Out of curiousity, what is your reason for not having Tbird remember/store your passwords?

Out of curiousity, what is your reason for not having Tbird remember/store your passwords?

1. memory exercise  :-)
2. pc at work with also personal accounts (I don't want that anybody hits "show saved passwords"; I know that from version 72 TB should ask for OS password when doing, I will check this when I will upgrade, waiting for extensions porting... Never wanted to set a master password, I preferred this way)
3. ability to choose day by day for which accounts I want to download and read new messages, by typing the password or not (since some are personal, sometimes I don't need to read them at work)

Have you ever considered using multiple Thunderbird profiles, one for work and another for personal accounts? Did you know you could even store your Thunderbird profiles in an encrypted container, which you mount (only after supplying the decryption password) before starting Tbird, then unmount it after you're done with Tbird? This way, the only password you keep entering is the decryption password, then you choose which Tbird profile to launch (work or personal, via convenient shortcuts; one for each profile). You won't have to worry about someone else accessing the Tbird password store, even if they had file access to the encrypted container, they would not be able to mount or unlock it without the decryption key.

Another option can be that somehow the passwords to fail to be saved/read because of some corrupted data or files. So then I will try this: First be sure that you have all your passwords (backup them somewhere). After that close TB and delete all saved passwords by moving* to desktop(?) key3.db, key4.db, cert9.db and logins.json files - start TB and it should ask again for all passwords.

To find those files - in TB at the top right of the Thunderbird window, click the menu button (or use the regular menu at the top), then select Help -> Troubleshooting Information. On profile area click Open Folder

p.s. moving* to desktop (but not just delete) it's important so you can have though a backup for those settings in case something is not right

Yes but I can't use them at the same time.

I know, but it's complicated and doesn't make any difference if I leave my pc for some minutes without locking; with the way TB worked the past years, everything was simple and reliable, now at least for me it's a little less reliable.

Yes you can.

Thank you very much for the suggestion. I removed the four files but unfortunately no difference. It even asks for password for IMAP inbox, then again if I click on IMAP Drafts of the same account, then again if I click on IMAP Sent, and so on; the second time I click on an IMAP folder, it doesn't ask again for password for some time (still I don't know exactly how long). Could it be a network setting, related to connection with IMAP servers?

Bye. Matteo

Can you post here your Thunderbird Troubleshooting information, so we can see your settings and try to duplicate on a same settings (on other servers, if it will be possible)?

At the top right of the Thunderbird window, click the menu button (or use the regular menu at the top), then select Help: Troubleshooting Information. Click the "Copy text to clipboard" button. Do not check the box "Include account names" Then paste (Ctrl-V), the text into your response here. We only need to see the sections down to and including the "Extensions" section, so you can delete the rest. Also, please mention us, from those accounts (will be account2, account3, and so on) which one(s) is/are with that issue and I would try to duplicate on a same settings (on other servers, if it will be possible).

Of course; sorry but the log is in italian. Thank you.

And you have this issue for all imap accounts from above or only for some of them?

And you have this issue for all imap accounts from above or only for some of them?

All of them. But today working at home I see that TB 60.3.2 I have at home, that always did as I told (password not saved, typed one time for session for each account), does the same! So it could be something related to network (a windows update??) or to providers' servers that all together (strange...) changed something in IMAP connections configuration, and not depending from Thunderbird... When I will have time I will recreate from scratch the user profile to see if something changes.

Thank you. Matteo

I just tried to duplicate your case on an imap account on v78.3.1 but I could not do it... Once the password was saved for that account I could not get on the same session a request for pass.

I have found though on my computer these lines different: network.cookie.cookieBehavior: 1 --> mine is 0 network.cookie.lifetimePolicy: 2 --> mine is 0 The values from my computer are default ones which are mentioned on https://developer.mozilla.org/en-US/docs/Mozilla/Cookies_Preferences while yours should mean some "restrictions"... Can you check on your 60.3 version how are those? Or maybe you can play directly on this non-working TB?
