How do I reset the information Thunderbird sends to my email provider (Names.co.uk)? This information has changed as I had to change my password on Outlook (i.e. Microsoft). I used Thunderbird to access this email for many years. So there is an existing account with <outlook.office365.com>. I would like to reclaim access to this account.

I recently became the webmaster for our local American Legion post and built a website through Hostinger. That service also offered a cost-effective email solution for us and I've created a number of email accounts for our office positions and some individuals by name. At the level of service we have with Hostinger, our website/email account domain is not the same as the email servers.

That's ordinarily not a problem, since most modern email applications can either pull domain email hostnames from registration records or gives the user a manual process to enter the email hostnames directly (in our case an IMAP and SMTP hostname belonging to Hostinger).

I had no problem using the manual configuration that Thunderbird supports to set up my first American Legion email address. Email was received immediately and testing outgoing email worked fine. Adding a second American Legion email address seemed to go well - email messages came in immediately - but the outbound testing failed with error messages that the sending client was not recognized.

That sounded like Thunderbird was not trying to authenticate with a password on the SMTP outbound even though I had indicated in the manual setup that a password was required (same as I had in the first American Legion account setup).

I checked the Thunderbird settings to see what saved passwords were recorded in the Password Manager and sure enough their were three IMAP host passwords but only two SMTP host passwords (the missing SMTP host password was for the second American Legion account).

I completely deleted the second American Legion account and tried again - just in case I had accidentally indicated no password needed for SMTP the first time - and got the same result (IMAP host password created, but not SMTP). I then tried deleting both American Legion accounts and then adding them back with the second account being added first this time. At least the problem was consistent - the first account added had both an IMAP host password record and a SMTP host password created; the second account created had only its IMAP host password saved.

I couldn't find a menu item for adding a host password in the Save Passwords settings menu; manually removing the IMAP password to force the system to ask for the password again only ended up with the IMAP host password being added back into the TBird Password Manager.

The version Linux Mint reports for Thunderbird is 1:128.11.1esr+linuxmint1+xia. As far as I can tell the issue only comes up when Thunderbird cannot auto-detect the email servers on its own and it only has a problem when more than one email account has to be added for a manually configured email domain.

Is there a TBird menu item I'm missing that would let me add the SMTP host password for the second account manually? Failing that, is this a known issue that has already been fixed by Thunderbird and should be forthcoming after that version is released as an update by the Linux Mint team?

I mistakenly deleted my password from Thunderbird's Password Manager. I have my primary password to log into Thunderbird but don't have the password to sign into my account. I've been trying for days now with no luck. How do I set a password in password manager?

Hello,

I recently reinstalled Windows on my computer and expected Firefox to sync and restore my saved passwords, as I had enabled Firefox Sync before reinstalling. However, after syncing my account, my passwords did not appear, and I am unable to access them.

I have already tried the following steps:

   Checked the sync status of my Firefox account.
   Ensured that I am signed into the correct Firefox account on my browser.
   Searched for any relevant troubleshooting steps but haven't been able to resolve the issue.

Could you please assist me in restoring my saved passwords or provide any guidance on how I can retrieve them?

Thank you for your help.

Best regards, Tameem

I want to switch from Outlook and use Thunderbird for our office emails. However there is no way to protect the saved email logins.

When I use a master password, every time the user opens Thunderbird, they need to enter the password but I do not want to give them the master password as it defeats the purpose. Ideally the master password or another setting should protect the saved logins only and the user should be able to login to Thunderbird without additional password.

So this means Thunderbird is not an application to use in office environments?

I have been receiving emails for my [email removed]@aol.com account on my pc, via Thunderbird, and on my ipad. Now both devices are saying the password is invalid. I have gone to the AOL website and changed the password and can receive emails at mail.aol.com. I have gone back to thunderbird and folllowed instructions to change the pw by deleting in settings and restarting Thunderbird and entering the new pw that AOL Mail recognises. But Thunderbird still says the pw is not valid. Any suggestions ?

Firefox is not saving my passwords. Every time I start up my laptop, all the saved passwords are gone. I have tried a refresh and a new install as well, but the problem persists. I have to sync to my other machine to restore them.

Greetings...

In regards to the Firefox Password Generator, I have two questions:

Q #1: Currently, the Firefox Password Generator appears to create random passwords that are 15 characters in length. Is there some way that I can increase the length of the randomly created passwords to a longer length, say 18 characters? Might this setting be contained at some location within "about:config" that I could edit?

Q #2: Currently, it appears that the only way to create a password for a new website in the Firefox Password Generator is when attempting to set the password while on a website. I would like to be able to create a password for a website from within the Firefox Password Generator itself. Is there some way that I could accomplish this task?

Thank you for your attention and assistance! Take care...

I have several email account set up with Comcast and am able to sign on to all but one with Thunderbird. That one gives me the login has failed message to enter new password or try again. I've compared the settings on that account with the others that work and they appear to be correct. However when I check saved passwords, that account is missing the smtp line for the POP account. At this point, I've run out of ideas of what to do, short of deleting that account on Thunderbird and setting it up as a new account. Help! Thanks.

I'm using Thunderbird on Windows 11 with my Outlook email account. I can receive email, but when I try to send an email, it tells me the password is wrong.

[moderator note, the following is unrelated] When I check the password in the Privacy and Security settings, Thunderbird has changed the password to a long string of letters, numbers, and symbols. I enter the correct password, but it keeps changing back to the incorrect password. I have tried deleting and re-adding the account. I have also uninstalled and reinstalled Thunderbird. Same result.

Spectrum had me change my password for one of my accounts on Thunderbird. I changed it with Spectrum. That account was working fine from Nov. 6 until today, Nov. 16; today, it decided that my password wouldn't work. I tried to change it when it asked at the time I was trying to send an email; it wouldn't take. I then went into "saved passwords" and tried to change it; it wanted a pin. This is my** first problem;** Norton has no idea what that is. Thunderbird asked for other sign-in methods including a Yahoo email, but I have no idea what it wants as it doesn't want the password for that Yahoo account. What is it looking for????

I deleted the account from Thunderbird's password manager. After my shutting down and reopening Thunderbird a few times, it finally worked --however, it didn't ask for a password and sent and received email just fine. Thunderbird now doesn't have that account listed in its password manager, but is giving me my mail and sending my mail out without asking me for a password. **This is my second problem.**

Since this is all combined, I'm sending both questions together; otherwise, I wouldn't do so. Does anyone know what's happening and how to get a password back as a necessity for that email account?

Dear Firefox-Support,

while using the iPad App in version 138.0 to generate a secure password today, this password was not saved. I was using the change password function on an account previously not known to my Firefox account. When I acknowledged the password change and was prompted to sign in in the same tab, neither the function that should remember the new password within the same session worked, nor was it saved with the other passwords.

I think it is unlikely you can help me find this password again, but I would like to make you aware, that this szenario might be an issue.

Hello,

I have to add the Password every time I open Thunderbird because I removed the Password myself after I read this:

<<<< ThundaMike Mozilla Staff 7/28/25, 9:15 PM more options Sounds like you are almost there.

Building off what @david said above, try this:

In Thunderbird, go to Settings > Privacy & Security.

Scroll down to the Passwords section and click Saved Passwords….

Find your email account in the list and remove the saved password.

Restart Thunderbird.

When prompted, enter your new password. >>>

My doing this it removed the .twc password Log In totally in that Settings. I do not see the "my twc.com" in the settings of Tools, Privacy & Security, then Saved Passwords in the list, I only see the Hotmail account settings I have in Thunderbird. Removing it like ThundaMike wrote really removed all the TWC Password and Information.

Can someone help me restoring or re-enter my Mozilla Thunderbird info back into Tools, Privacy & Security, then Saved Passwords so I do not have to type in the Password every time I open Thunderbird.

Thank you so much for your time and efforts I truly appreciate it.

When made to change my password by my email provider, instead of deleting my old password in Thunderbird I accidentally deleted the entire saved login (Thunderbird > Settings > Privacy&Security > Passwords > Saved Passwords > then deleted the entire saved login instead of only deleting the old password). When I tried adding my account login back to Thunderbird using “+ New Account”, it gives me an error message that my incoming server already exists. I'm trying to get my old saved login back without doing any more harm. I can still get into Thunderbird but it won't connect to the server (my login credentials now fail). I can still see and read my old emails but it won't retrieve any new emails. Is there a way to get my old login credentials back or re-enter them into Thunderbird? If not, are there files and folders I can copy from my old saved Thunderbird Profile directory into my active Profile directory to be able to login to my account again while keeping my local folders? I saved a lot of my email to my local folders, so I'm hesitant to overwrite my Mail folder (and even my ImapMail folder) for fear of losing my existing folders, especially my local folders.

The Thunderbird password I've used for YEARS (and is stored in "Saved Passwords") no longer works. I have two laptops with the same password, and they both ceased (on the same day) allowing downloads (or sending) of emails. This occurs on both my laptops -- one has TB version 115.10.1 w/ Windows 10, and the other has 140.5.0esr w/ Windows 11. It also occurs on my iPhone when trying to access the mail server.

Could the problem be the mail server itself?
