About UUID v4
UUID (Universally Unique Identifier) v4 generates 122 bits of randomness using a cryptographically secure random number generator. The probability of collision is astronomically low — approximately 1 in 5.3 undecillion (5.3 × 10³⁶). Safe for use as primary keys, session tokens, and unique identifiers.
