The best way to prevent accidental loss of your identity is to use a dedicated security key as a registered device and keep it in a safe place. We always recommend you add multiple devices to your Internet Identity and at least one actual security key. In case you lose a device, you should register as many devices as possible to prevent you from losing access to your applications.
The minimum backup setup we should recommend for now is:
- Security Key
- Phone with Biometrics (Don’t clear cache if Mac or iOS!)
- Recovery Phrase
