Password Manager od Tazmeen Kazmi

A simple, lightweight password manager that keeps your logins on your own computer. No account, no sync, no tracking, and nothing is ever sent anywhere.

Your logins are locked with a master password. The vault locks itself after a time you choose, and always when Firefox closes.

What it does:

Fill logins from the toolbar, or from a small icon inside the login field
Warns you before filling a login on a site it wasn't saved for, so a lookalike page can't collect your password
Offers to save a login after you sign in, including JavaScript logins and two-step sign-ins like Google and Microsoft
Custom fields: keep extra values such as PINs, security answers or message templates, and point each one at a field by clicking it on the page. This works in rich-text editors, comment boxes embedded from other sites and modern web components, and values can be several lines long
Password generator with length and character options, plus a strength meter
Copy a username or password with one click; the clipboard clears itself after 30 seconds
Organise your logins with search and color-coded cards
Backups: an encrypted export protected by your master password, and a plain-text export
Two themes, Sky and Peach
Designed for privacy-conscious users who want control without the bloat of traditional password managers.

Updating from an older version: your saved logins are kept. The first time you open the add-on you'll be asked to create a master password, and your logins are re-encrypted with it.

Requires Firefox 115 or later.
