Alternative 2FA app with offline mode

Build a 2FA app that works offline for travelers and remote workers. Offer encryption without cloud dependency.

Why now

Enterprises distrust cloud-only 2FA after recent outages, creating demand for resilient alternatives.

Who for
Security-conscious professionals
Business model
Enterprise licenses, premium features
Effort
A few weeks

Business travelers frequently lose access to 2FA codes when without internet. A native app storing encrypted tokens locally would solve this.

Focus on iOS/Android apps with biometric unlock and manual backup options. Charge through enterprise licenses or premium individual features.

Start with Google Authenticator-compatible TOTP generation. The risk is competing with free offerings from big tech.
