The UUID v4 & 2FA Secret Key Generator produces cryptographically random 128-bit Universally Unique Identifiers (RFC 4122 Version 4) and RFC 4648 Base32 secret keys in bulk. With $2^{122}$ possible v4 UUID combinations, the probability of generating a duplicate is virtually zero—making them ideal for database primary keys, session tokens, and cryptographic seeds.
Generate up to 500 UUIDs or Base32 secret seeds with a single click, formatted with or without hyphens and uppercase/lowercase.
Create compliant 16 or 32-character Base32 authentication secrets for Google Authenticator and 2FA deployments.
Select between standard UUID v4 or 2FA Base32 secret keys.
Select how many keys to generate (1 to 100+) and toggle uppercase or hyphen formatting.
Copy the batch directly to your clipboard or download them as a clean text list.
To have a 50% probability of finding a single duplicate collision, you would need to generate over 2.7 quintillion UUIDs ($2.71 \times 10^{18}$).
Yes. The generated Base32 keys use the standard A-Z, 2-7 alphabet specified in RFC 4648 and are 100% compatible with RFC 6238 TOTP authenticators.
