OTP Authenticator App

Protect every account with a fast, private authenticator app. KeyVault
generates 2FA OTP codes offline, encrypts them on your device, and restores
them in seconds if you switch phones.

KeyVault is a two-factor authentication app that replaces SMS codes with
secure, time-based one-time passwords (TOTP). Add an account once and get
a fresh 6-digit verification code every 30 seconds — no internet, no
account sign-up, no tracking.

WHAT YOU CAN DO

• Scan a QR code to add an account in one tap
• Enter a setup key manually when no QR code is shown
• Generate 6-digit login codes that refresh automatically
• Copy a code with a single tap at sign-in
• Search and reorder accounts so the ones you use most stay on top
• Export an encrypted backup and restore it on a new device
• Import existing accounts when migrating from another authenticator

WORKS EVERYWHERE 2-STEP VERIFICATION IS SUPPORTED

KeyVault is compatible with any service that uses standard TOTP two-factor
authentication — email, social networks, cloud storage, developer tools,
banking portals, gaming accounts and crypto exchanges. If a service shows
you a QR code during 2FA setup, KeyVault can secure it.

WORKS OFFLINE, BY DESIGN

Codes are generated on your device using open TOTP standards, so the app
works in airplane mode, on a plane, abroad, or with no signal at all.
Nothing is uploaded, and there is no account to create.

YOUR DATA STAYS YOURS

• Accounts are encrypted on the device
• No sign-up, no email, no cloud account required
• No ads and no tracking
• Backups are encrypted before they leave the app

KEYVAULT PRO

Upgrade for power users managing many accounts:

• Store unlimited accounts
• Organize accounts into custom categories
• Assign colors and icons for instant recognition
• Personalize the app with custom themes, including dark mode
• Lock the app with biometrics or a PIN

ACROSS YOUR DEVICES

KeyVault runs on Android, Windows and Linux, so your verification codes
are available at your desk as well as in your pocket.

WHY PEOPLE SWITCH TO KEYVAULT

SMS codes can be intercepted through SIM-swap attacks, and many
authenticator apps make it painfully hard to move your accounts to a new
phone. KeyVault fixes both: strong, offline multi-factor authentication
plus a backup and restore flow that takes under a minute.

GETTING STARTED

1. Open the 2FA or security settings of any website or app
2. Choose "authenticator app" as your verification method
3. Scan the QR code with KeyVault
4. Enter the 6-digit code to confirm

Tip: create an encrypted backup right after you add your first account.
