What if I lose the device my passkey is saved on?
If you have SMS set up on your account, sign in using that method, then go to Settings > Security and remove the passkey associated with the lost device. Once removed, it can no longer be used to access your account. You can then register a new passkey on a device you still have.
If SMS is not set up and your passkey is your only sign-in method, contact us at support@augment.market.
