A PIN (personal identification number) is never as good as a good password because its character set is drastically limited to only ten numerals (0-9), and a PIN is often shorter than a password. Shieldpay requires a password and PIN upon registration and thereafter only a password to log in. We will only ask you for your PIN when you fund or withdraw money from the Shieldpay Vault.
A good PIN is long and random. A six-digit PIN as required for the Shieldpay Service requires trying at most only 100,000 combinations to achieve a successful guess. Avoid predictable sequences such as “12345” or “36987” which on an ordinary keypad is simply down the right side then over across the bottom row.
