Authenticator with backup and recovery

Build a 2FA app that securely backs up and restores codes across devices.

Why now

As security concerns rise, users need reliable alternatives to vendor-locked authenticators.

Who for
Security-conscious professionals
Business model
Premium subscriptions
Effort
A few months

People lose access to accounts when switching phones or losing devices with 2FA enabled. A cross-platform authenticator app with encrypted cloud backup would solve this.

Offer end-to-end encrypted sync between devices, plus printable emergency codes. Charge for premium backup slots or business team features.

MVP: Basic TOTP generator with manual backup export. Risk: competing with free options from big tech.
