Winter Password Manager od Tyler H

Winter Password Manager lets you use your existing KeePass vault (.kdbx) in Firefox. It opens the vault from your Dropbox, decrypts it only on your device, and fills your logins as you browse. Your master password is never stored or sent anywhere.

Features
• Suggests matching logins when you click a username or password field, including multi-step sign-ins
• Fills two-factor (TOTP) codes stored in your vault
• Offers to save new logins and update changed passwords
• Generates strong passwords and passphrases
• Search, view, add and edit entries from the toolbar button
• Locks automatically, and clears copied passwords from the clipboard after 30 seconds
• Works with KDBX 3 and 4 vaults, so the same file opens in KeePass, KeePassXC and other KeePass apps

Privacy
The only data that leaves your device is your vault file, still encrypted, sent to and from your own Dropbox so your changes are saved. No analytics, no tracking, no developer servers.

Requires a Dropbox account with a KeePass .kdbx file in it. Works with Dropbox; not affiliated with or endorsed by Dropbox or the KeePass project.
