PowerSafe

PowerSafe keeps your passwords on the devices you already own: your phone and your computers. There is no account to create and no company vault holding your logins, so there is nothing central to break into. NO ACCOUNT, NO CLOUD You choose a master password, and that is the whole of the setup. Your logins are stored on your devices and travel only between the devices you add, directly, over your own network. Unidatum never receives your vault. ADD A DEVICE BY HOLDING UP A CODE One device shows a square code and the other scans it. It works either way round, so a computer can join a safe that started on your phone. PowerSafe runs on Android, Windows and macOS. OPEN IT WITH YOUR FINGERPRINT Your master password unlocks the safe the first time; after that your fingerprint will do. PowerSafe locks itself after a few minutes idle, or shortly after you switch to another app. COPY A PASSWORD OFF ANOTHER SCREEN Point the camera at a password shown on another screen and PowerSafe reads it in, on the phone itself. It shows you what it read, marking any character it was unsure of, so you can check it before saving. FILLS IN LOGINS ON YOUR COMPUTER The PowerSafe extension for Chrome and Edge shows the logins that match the page you are on and fills one in, asking the PowerSafe app on that same computer. SEALED BEFORE IT IS STORED Every login, its title included, is encrypted with XChaCha20-Poly1305 under a vault key that your master password opens through Argon2id. The safe stays out of Android's cloud backup. ALSO • Search as you type • Change the master password on any device; the others follow • Remove a lost device once, from any of the others • Edits made on two devices while apart settle on their own • Copied passwords are cleared from the clipboard after 30 seconds • Light and dark themes • No ads, no analytics, no tracking GOOD TO KNOW Your master password cannot be reset or recovered, by you or by us, so choose one you will keep. Devices sync while PowerSafe is open and they can reach each other, on the same network or over Tailscale. Keep PowerSafe on more than one device so that losing one never costs you your passwords.
