Check compatibility

Your device must have biometric hardware and at least one face/fingerprint enrolled in system settings.

  • Consider using a password manager

​
Session Timeout

If your Firebase session is too old, password changes may fail with: 
Error: "No se pudo actualizar. Es posible que debas iniciar sesión nuevamente."
Solution:

  2. Log back in with your current password
  3. Immediately go to Security and change your password

Security Best Practices

Use Biometrics

Enable Face ID or Fingerprint for quick, secure access without typing passwords.

Strong PIN

Avoid 1234, 0000, or your birthday. Use a random 4-digit combination.

Regular Updates

Change your PIN and password every 3-6 months.

Secure Device

Always lock your phone with a passcode. PARKINMX security is only as strong as your device lock.
