This error message appears when the passkey used cannot be assigned to an existing enovetic ID account. This can have several causes:
You have not yet registered for an enovetic ID. In this case, you must first complete the registration before you can sign in with a passkey.
You set up a password instead of a passkey during registration. In this case, sign in with your password and then add a passkey via the Account Manager: How do I add a passkey to my account?
You selected the wrong passkey from your password manager when signing in. If you have multiple passkeys saved, make sure you select the one assigned to your enovetic ID.
The passkey was created on a different device or in a different password manager. Try signing in with the device or password manager with which you originally created the passkey.
If none of the above situations apply to you, you can reset your credentials. More information here: Reset credentials
