API Token Generator
Cryptographically secure tokens for APIs, secrets, and applications.
Length: 16
Format
API keys, session tokens, and secrets should always be created with a cryptographically secure random generator. Choose from Base62, Base58, Hex, or NanoID.
Frequently asked questions
Base62 is the default for API keys. Base58 drops 0, O, I and l, which helps when people retype or read out the value. Hex suits systems that expect a hexadecimal string. NanoID gives you a URL-safe identifier.
Aim for at least 128 bits of entropy — roughly 22 characters in Base62 or 32 characters in hex. For long-lived secrets that cannot be rotated regularly, 256 bits is the safer choice.
Both use the same procedure, and the API logs nothing. If you want maximum control, use the in-browser generator: the value is then created on your device and never travels across the network.
