2FA AUTH — SecureVault: 2FA Authenticator & Password Manager

Your accounts, protected in one place. 2FA AUTH (SecureVault) combines a fast two-factor authenticator, an encrypted password manager, and a QR code scanner in a single app, so you don't need three separate apps to stay secure.

WHY 2FA AUTH
• All-in-one security — generate time-based 2FA codes, store passwords, and scan QR codes without switching apps.
• Zero-knowledge encryption — your data is encrypted on your device before it is ever backed up. We cannot read your passwords or codes, and neither can anyone else.
• Works with the services you already use — Google, GitHub, Amazon, Discord, Netflix, PayPal, Instagram, Slack, Spotify, LinkedIn, Dropbox, WhatsApp, and hundreds of other TOTP-based accounts.
• Import in seconds — bring your existing 2FA accounts over from other authenticator apps, including Google Authenticator export codes.
• Built-in setup guides — a searchable directory of 50+ popular services with step-by-step instructions for turning on 2FA.

TWO-FACTOR AUTHENTICATION
Add an account by scanning its QR code or entering the setup key manually. 2FA AUTH generates standards-based, time-based one-time passcodes (TOTP) that refresh automatically, with a countdown so you always know when a new code is coming.

PASSWORD MANAGER
Store logins, notes, and card details in one encrypted vault. Every entry is protected the same way your 2FA secrets are: encrypted on-device with AES-256-GCM before it ever leaves your phone.

SIGN IN YOUR WAY
Get started using your existing Google or Apple ID. No new account password to create or remember.

SECURITY, BY DESIGN
• AES-256-GCM encryption for every stored secret.
• Argon2id key derivation to protect your master password.
• A zero-knowledge architecture — your master password and unencrypted data never leave your device.

2FA AUTH PRO (Optional)
The core 2FA authenticator and a starter password vault are free to use. 2FA AUTH Pro adds unlimited password storage, automatic encrypted cloud backup, and the ability to restore your codes and passwords onto a new device. Pro is offered as auto-renewing subscriptions or a one-time purchase:
• Monthly — every month Renew.
• Annual — every year Renew.
• Lifetime — one-time purchase, no recurring charge.
Payment is charged to your Apple ID at confirmation of purchase. Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period, and your account will be charged for renewal within 24 hours before that period ends. Manage or cancel anytime in Settings on your device under Apple ID > Subscriptions. Prices are shown in USD and may vary by region.

ADVERTISING
A small number of free-tier screens — Tools, Setup Guides, and the password generator — may show ads served by Google AdMob. Ads never appear on your authenticator list, your password vault, the unlock screen, or during backup and restore. 2FA AUTH Pro removes ads entirely.
