If sign-in fails with a message that your device clock is out of sync, VocaLingo cannot validate the one-time login code because security tokens depend on correct time.

Exact message

Your device clock is out of sync. Go to Settings → General → Date & Time and enable "Set Automatically".


Fix on iOS

  1. Open the device Settings app.

  2. Go to General → Date & Time.

  3. Turn on Set Automatically.

  4. Return to VocaLingo and request a new login code.


Fix on Android

  1. Open Settings → System → Date & time.

  2. Enable Use network-provided time and time zone.

  3. Retry login in VocaLingo.


Frequently asked questions

OTP and session security use time-based checks. Large skew causes validation to fail.

Toggle airplane mode, reboot the device, then try again.

Use automatic time zone when possible.

Check the computer system clock and time zone in OS settings.
