About Spare Key

Spare Key is a small reference site about regaining access: what to do when the verification code never arrives, when the authenticator app went down with the phone, and when the number on the account stopped being yours.

Editorial approach

Every guide is built from primary sources: standards documentation, regulatory filings, vendor specifications, and hands-on deployment experience. We update articles when the underlying facts change and note the revision date on each page.
