Why is Zero Password Manager more trustworthy? - We have been developing many verifiable security technologies instead of "Please trust the developers". - We have consistently improved the security instead of always saying, "The UI has been updated again". γSolid security modelγ - True offline keeps your data isolated from the Internet. Your passwords are only stored on your phone and can never be uploaded to the cloud secretly. - Security chip encrypts your data on your device. Mobile wallets use the same chip to protect your card information, so if you trust the mobile wallet, you can trust Zero. - Neither require sign-up nor collect personal information. We don't have any information on you and don't know who you are, let alone bother you with ad tracking. - Biometric authentication to safely unlock the app. Or you can set a master password for an extra layer of protection. Of course, we also use other standard encryption technologies like AES-256 and PBKDF2. γFeature-rich and easy to useγ - Account security templates Hundreds of account templates, including Apple ID, Capital One, Binance, Epic, etc., can hold all sorts of security information you can think of, such as passwords, recovery keys, and security q&a. Some templates also have security tips. - Save payment cards As long as you enter the card number, Zero password manager can automatically identify the card issuer, card organization, etc. It's easier than ever to store payment card information. - Autofill passwords Fill in your username and password on mobile apps or websites with only two taps. Zero password manager will also automatically check the security of the app or website you are filling in. - OTP authenticator Zero password manager integrates OTP (one-time password) authenticator to facilitate 2FA. You can keep passwords and OTPs in just one record. - Desktop browser extension With the extension, you can scan QR codes with the app to safely fill passwords into desktop browsers (Safari, Chrome, Edge, and Firefox). - Password generator Besides the most basic options like numbers, letters, and length, you can also choose to include certain special symbols, emojis, etc., in your passwords. It works for websites with complex password rules. - Find back master password Forgot your master password? Don't worry. You can ask your friends to help find it back; they can't peek at any data. More great features like password meter, password timeline, password change reminder, etc. are all available in Zero password manager.
Authenticator

This is not a basic two-factor authentication app. It is a full personal security platform β codes, passwords, an encrypted vault, a private browser and autofill β built for people who take account security seriously enough to want everything in one place and nothing left unprotected. Use two-factor authentication on your accounts but manage your codes, passwords and sensitive files across three or four different apps and want everything consolidated under a single layer of encryption and Face ID. Have lost access to accounts before because you changed phones and had no encrypted backup of your 2FA codes β and want Cloud Sync that keeps everything recoverable without compromising what is stored. Type passwords and copy 2FA codes manually every time you log in because your authenticator and your password manager do not talk to each other β and want Auto Fill that handles both in one step WHAT YOU GET INSIDE 2FA Authentication β secure TOTP and HOTP code generation for any account that supports two-factor authentication, codes refreshed every 30 seconds QR Scanner β instant account setup by pointing the camera at any 2FA QR code MFA and OTP Support β full multi-factor and one-time password compatibility across all standard authentication formats Backup Codes β stored recovery codes for every account so a fallback always exists when the primary device is unavailable Password Manager β encrypted credential storage for every login, organized and accessible without switching apps Secure Vault β end-to-end encrypted storage for sensitive files, recovery keys, private notes and anything that does not belong in a standard notes app Private Browser β built-in browser for sessions that should stay separate from your regular browsing history, with vault access directly inside it Auto Fill β automatic code and password entry across apps and websites so nothing needs to be copied or typed manually Cloud Sync β encrypted backup across all your devices so your full setup is recoverable on any new device from the moment you sign in Widgets β home screen and lock screen access to your most-used codes without opening the app Encryption β end-to-end protection applied across every feature, every stored item and every synced file SUBSCRIPTION & ACCESS Important: Subscription required; no free content.
