Thunderbird is regularly (at least once a week at random times) forgetting all my passwords. I have tried all the suggestions I can find (deleting various system files etc) and nothing changes. The passwords work for several days, but eventually when I start Thunderbird it has lost all my passwords. This is something that started about two or three months ago; before that, I never had a problem.

P.S. Yes, I select "use password manager" (or whatever it's called) every time I have to put in the passwords.

I have 3 email accounts which i unified. when log in I get prompted to enter password for all three accounts which I do, then I get prompted again to enter the password to all Password Manager to save my passwords which I do not want and therefore I uncheck it for all three; I then get prompted again for all three which I enter password, then I get imap login error on my main account which I click cancel a few times before it goes away,

I use Thunderbird portable. How do I fix this issue. it should be that one enters the password for each account once not three to four times. I do not want to use Password Manager to Save my accounts.

Also if ever I have to change password how do I do that? thank for your help.

I have the portable version, download from portable apps website.

Since changing my gmail accounts settings in thunderbird under Synchronization and storage so as not to store a local copy of emails. Thunderbird, after a while, is no longer able to authenticate to imap.gmail.com. If i delete the associated oauth2 saved passwords, restart and regrant access. Thunderbird is ok for a couple of hours but then fails again later. Thunderbird ran fine for a couple of days before i changed the synchronization settings.

Any ideas on how to eliminate this annoyance?

Twice in the last fortnight Thunderbird has lost all email passwords - the Tools/Settings/Privacy and security/Saved passwords just leads to a blank box where the passwords usually are. Thunderbird will no longer collect email and keeps asking for passwords for email accounts. This happens even when the option to 'save password' has been selected. I think this is probably happening at the point when the PC is rebooted. Thunderbird version 153.1.1esr (64 bit) and Windows 10. Using System Restore has not resulted in recovery of passwords. Several different email accounts/email providers are involved - outlook.com, tiscali.co.uk and zohomail.eu. Broadband provider is Zen.

I notice that the Appdata/Roaming/Thunderbird/Profiles/w2anb37y.default folder contains a number of files named with such names as 'logins.json-8.CORRUPT' - with 'Date Modified' being mostly either 17th August or today 31st August - so it might look as though password data is becoming corrupted.

Can you assist?

mozillla or thunderbird is changing an email password blocking my access to send email from account it will not accept the password i set for account, in saved passwords it has a huge password stored that i did not set ,,also that password is not accepted it was hard enough to get that email set up on a w10 pc and a w11 laptop, this problem started when i allowed an update to t-bird, further updates have not helped on update 115.10.1, it want to update again, i have use mozilla and t-bird for 30+ yrs and the problems keep getting worse not better and has become almost user unfriendly. to add an email, should require 1)user name,, 2) email address, 3)password. thats it , it shouldnt require a IT degree to set up the rest

I have 8 email accounts. Four of them use my service provider; "@Bell.net", and four of them are gmail accounts. When I open my Thunderbird app two things happen. A Google web page opens asking "Mozilla Thunderbird Email wants access to your Google Account". with a reference to one of my gmail addresses. This web page opens when I shut down Thunderbird as well. Secondly, Thunderbird asks me for the passwords for each of my four Bell accounts. I have tried everything suggested, deleting passwords, deleting profile files, you name it. I've been at this on 4 separate occasions, with this last one lasting 2+ hours. I'm at a complete loss. When I suggest deleting Thunderbird and reloading it, I'm told that may not fix the problem because it would still reference potentially corrupted files. Please help!

I moved, tried to get old wireless printer going. Had driver issues. Gave up bought newer printer. Somewhere in there Firefox or Windows updated. Wiped out all my passwords. I have gone and started putting passwords back in. Firefox says it's saving them, but it's not. I also had just connected firefox to my cell. I tried a history recover, which doesn't seems to work either. I have to go to Explorer to get into Ancestry account and now can't get into my Family Tree account. I'm so confused. My HP laptop is only 3 or 4 yrs old. and nothing is reading as a virus or bug. Any suggestions. I'm about to cry with all the information on here. I have backed up on external drive, but not sure that is going to work. HELP

I have 8 TB emails. Every morning when I open email, all passwords need to be re-entered, sometimes 2-3 times a day. I have done everything YouTube has suggested and looked for similar issues and fixes on the forum, including creating an initial PW to open the main TB email account. No success yet! I have a PC; if that helps answer the question. I also recently downloaded an update, which did not fix it. Any suggestions would be appreciated. Thanks in advance! Carl

I have 10 email accounts I have to monitor. When I set up Thunderbird on Windows, I entered all the account info and the passwords. I checked the box 'use password manager'. This worked well for a few days. After several days, I started the app again and it asked for every password again. I entered all the passwords again. This happened several more times. I sought help for the bug, but found none. Someone suggested deleting password database files in the Thunderbird data folders. This did not help. Someone else suggested that CCleaner may be deleting password data files, so I added the entire Thunderbird data folder to the scanner exclusion list. Yes, this may be a security risk, but I need this app to work, as I have not found any other app that even begins to get the job done. Ready to start looking for another email app now, unless someone can fix this problem. It is not reasonable to expect me to lookup and restore 10 passwords every time I check my mail.

After moving the data file to a new windows 11 machine, the Password Vault no longer remembers passwords. How do I fix? Online searches have told me to delete several files in the Profile folder. I have done this several times w/o success. What are my options other than to find another email client? Thanks, Hank

After the latest update to Firefox (154.0.1) on Linux Mint, I discovered that ALL my passwords have been deleted. I recreated them and the next day they were missing again. I've been a faithful Firefox user since its early days. It was a good run but this is unacceptable and I'm going to delete FF and move to another browser. Too bad because I did like FF.

Once again after Firefox update it don't save my email address or password for Royal Caribbean website. It used to but not now again. Chrome does save both of them. I have tried everything even all what AI tells me to try. Nothing works. This is about the 3rd time this has done this on Firefox. Thank You.. I have Windows 11.

I've been using Thunderbird on our pc for decades, but it I believe the last software update has corrupted the "Password Manager". Since then, almost every time I attempt to log in, I receive the message about my password is incorrect, even though I have changed and checked the box that states something like "use Password Manager" for it. This is naturally "driving me crazy". Is there going to be a fix or is it just my problem? Thank you!

I attempted to get into an account and my password did not appear. When I attempted to get into my password manager, it has disappeared completely and I have no access to that information

I've safely saved many, many passwords in Firefox for a long time. Then one fine day a month or so ago, I found out that ALL of my passwords had been wiped out! Ever since then, I started saving my passwords in a .csv file and then uploaded the file to the Passwords page. The passwords keep getting wiped out anyway. I can't find a way to stop this from happening.
