VaultSpec is a secure authenticator app for two-factor authentication (2FA). It generates the one-time codes you need to sign in, keeps every secret encrypted on your phone, and backs them up so a lost phone never locks you out.
Scan a QR code, unlock with your fingerprint, tap a code to copy it. Works offline, no account needed.
WHY CHOOSE VAULTSPEC AUTHENTICATOR
• AES-256 encryption: every 2FA secret is locked with a vault password only you know
• Biometric unlock: fingerprint or face unlock, backed by your phone's secure hardware
• Offline authenticator: codes are generated on your device, no internet needed
• No ads, no tracking: no advertising or analytics SDKs
• Open source: the code is public, so anyone can verify how your data is handled
ENCRYPTED CLOUD BACKUP & RESTORE
Losing or switching phones shouldn't lock you out of your accounts. VaultSpec backs up your authenticator codes so that only you can read them:
• Your vault is encrypted on your phone before upload. Your vault password never leaves your device, so we can't read your codes
• Automatic backups daily, weekly, every two weeks or monthly, with a notification when done
• New phone? Sign in, enter your vault password, and all your accounts are restored
• Prefer local only? Scheduled encrypted backups to a folder on your phone work the same way
• Delete your account and all backups from inside the app at any time
FAST, CLEAN, EASY TO USE
• Light, dark and pitch-black (AMOLED) themes
• Icons for 3,000+ services
• Search, categories and filters for many accounts
• Tap to copy; optional hidden codes that reveal on tap
• Auto-lock after a time you choose
• Quick QR code scanner, or enter a setup key manually
WORKS WITH ALL YOUR ACCOUNTS
VaultSpec supports TOTP (time-based one-time passwords), the standard used for 2-step verification and multi-factor authentication (MFA) by Google, Microsoft, GitHub, Amazon, Discord, Proton, crypto exchanges and thousands more. If a website offers "authenticator app" as a sign-in option, VaultSpec works with it.
ABOUT YOUR VAULT PASSWORD
Your vault password is the key to your codes and backups. We don't store it and can't reset it, so keep it safe.
