Gerador de PIN — Crie códigos numéricos seguros

A PIN (Personal Identification Number) is a numeric code used for authentication. PINs are commonly used for ATM cards, mobile devices, and door access systems.

For most purposes, a 6-digit PIN provides a good balance of security and usability. For high-security applications, use 8 digits.

PINs provide limited security due to their small keyspace. Use them only where the system includes rate limiting or lockout after failed attempts.
