Verify who you're really talking to

Protect yourself from voice cloning and impersonation scams. SimplyAuth uses time-limited verification phrases that only you and your contact can see.

Why SimplyAuth?

Simple, secure identity verification for the people you care about.

Voice Phrase Verification

Time-limited 4-token phrases that expire in 60 seconds. Two words and two numbers that only appear on your screens.

Scheduled Check-Ins

Set a timer. If you don't check in, your connections get notified automatically. Perfect for solo outings.

Distress Alerts

A hidden duress code lets you silently alert your trusted connections if you're in danger during a verification.

Private & Secure

No voice recording. No call interception. Phrases are generated fresh each time and auto-expire after use.

How It Works

Three steps to verify anyone's identity

1

Add a Connection

Share an invite code or scan a QR code to link with someone you trust. It takes seconds.

2

Get a suspicious call?

Tap "Verify" on your connection's card. A unique, time-limited phrase appears on both phones simultaneously.

3

Read the phrase aloud

If what they read matches your screen, it's really them. If not, hang up immediately.

Safety Feature

Scheduled Check-Ins

Going somewhere alone? Set a timer. If you don't tap "I'm OK" before it expires, your selected connections get an automatic alert.

  • Preset or custom durations up to 24 hours
  • Add an optional note for context
  • Choose which connections get alerted
  • Extend by 30 minutes if you need more time

See it in action

Watch how SimplyAuth verifies a trusted connection in seconds — from adding a contact to confirming who's really on the other end of the line.

SimplyAuth shows a matching rotating phrase on both phones during a call. If the phrase the caller reads aloud matches what's on your screen, it's really them. Ten seconds of friction for complete certainty — and peace of mind when it matters most.
