Preguntas frecuentes
SHA-1 vs SHA-256 for TOTP — does it matter?
SHA-1 is the standard (RFC 6238) and compatible with all authenticator apps. SHA-256 is more secure but not universally supported. Stick with SHA-1 for compatibility.
How many backup codes should I provide?
8-10 single-use codes. Store hashes only (like passwords). Mark as used after each use. Allow regeneration which invalidates all previous codes.
