Generate clean, high-entropy passwords excluding all punctuation marks and symbols for seamless compatibility with restrictive systems.
Eliminating punctuation drops the character pool from 95 characters to 62. However, because entropy scales linearly with length, simply adding 2 to 3 characters completely recovers the lost security margin.
An 18-character password without special characters offers 62^18 ≈ 1.8 × 10^32 combinations, keeping your accounts fully secure against brute-force attacks.
Older web applications often use poorly parameterized database queries or shell execution strings vulnerable to SQL injection (SQLi) or command injection. To compensate for insecure backend code, they disallow symbols entirely.
We recommend at least 18 to 20 characters when special characters are excluded. This offsets the smaller character pool and guarantees more than 105 bits of entropy.
