Anything your phone's passcode unlocks is only as private as your phone. PassKeep has a lock of its own — a master password only you know. For the handful of things that shouldn't share a door with everything else. A LOCK OF ITS OWN Face ID opens PassKeep in a second. Behind it is a master password you set and nobody else has, including us. Hand someone your unlocked iPhone and your vault is still shut. MORE THAN PASSWORDS Card numbers and PINs. Wi-Fi codes. Passport and ID numbers. Recovery codes. The note you keep meaning to delete from Notes. Every entry is yours to shape — add the fields you need and name them yourself. ONE VAULT, EVERY APPLE DEVICE Turn on iCloud sync and the same vault is on your iPhone, iPad and Mac. It travels through your own iCloud, with Apple's end-to-end encryption. No PassKeep account to create. No PassKeep server in the middle. We never see it. ENCRYPTION, NAMED AES-256, with the keys held in the iOS Keychain. Nothing proprietary, nothing to take on faith. YOUR BACKUP IS A FILE YOU HOLD Export an encrypted backup whenever you want — free on every plan, in a documented format. Import it on a new iPhone in a minute. You are never locked in, including out of PassKeep. WHAT PASSKEEP DOES NOT DO It does not fill passwords into apps and websites on iPhone. Keep using whatever you use for that. PassKeep is for the things you don't type every day and can't afford to lose. We collect anonymous crash and usage data to fix what breaks. You can switch it off in Settings. FREE 5 entries. Face ID. Backup and export. PRO Unlimited entries. iCloud sync across your Apple devices. Password generator. Full security analysis. In market since 2016. Built in the EU.
