Why does Create or Login return a signature error?
Double-check the string you sign, the host value (domain only), and the HMAC key. Reusing a nonce will also cause failures.How long are JWTs valid?
JWTs are short-lived. UseAccount/Refresh before expiry or log in again.
Why is my account still disabled after Create?
New accounts are disabled until the email address is verified withAccount/VerifyEMail.
What happens if Refresh fails?
If the JWT is expired or invalid, you must log in again withAccount/Login.
Does Recover reveal if an account exists?
No.Account/Recover intentionally returns no success signal to avoid
information leakage. A 422 error is the only explicit case, when multiple
accounts match and no userName is supplied.
