Frequently asked questions
How is Base32 different from Base64?
Base32 uses a 32-character, case-insensitive alphabet and avoids easily confused characters, which makes it more robust for manual entry - at the cost of longer output than Base64.
Where is Base32 used?
It is widely used for two-factor authentication (TOTP) secret keys, some DNS applications and identifiers that must be typed by hand.
