Choose a PIN from 3 to 10 digits
A three-digit code has 1,000 possible sequences, a six-digit PIN has 1,000,000, and a ten-digit code has 10,000,000,000 when leading zeros and repeats are allowed. Each added digit multiplies the complete search space by ten.
Numeric password generator or PIN generator?
A digits-only value is a PIN or access code, not a full account password. Six uniformly generated digits provide about 19.9 bits; ten digits provide about 33.2 bits. Use numeric codes only where the device or service limits failed attempts. Otherwise choose a longer password containing letters and other characters.
What about an 8-digit password?
If the requirement means eight numbers, choose the 8-digit option on this page. If it means any eight characters—including letters or symbols—use the 8-character password generator. An eight-digit PIN has about 26.6 bits and still depends on lockout protection.
Short PINs need stronger safeguards
Three-, four-, and five-digit PINs have small search spaces. Keep the requested option available for legacy devices and fixed formats, but rely on attempt limits, lockouts, or device protections rather than treating a short numeric code as a strong standalone password.
Why repeats and leading zeros are allowed
Removing values such as 0007 or repeated digits makes the remaining set smaller and biases the output. Uniform generation treats every sequence of the chosen length equally.
Need exactly four numbers?
Use the dedicated 4-digit password generator for an immediate batch of four-number codes and a clear explanation of the 10,000 possible combinations.
Do not reuse a PIN
A PIN for one device or account should not become a universal secret. Generate a new one for each separate use.
