Get back in without a passkey
Enter the address on your account. We will send you a link that signs you in once, for long enough to add a new passkey. It does nothing else. Losing a passkey does not affect your licence: the licence is a file on your own machine and is checked there, and your forum badge is looked up from your address. Both will be as you left them.
If you still have a passkey, you can sign in with it.
