Strong Password Generator — Maximum Security Passwords
Generate extra-strong 20-character passwords with mandatory symbols for high-security accounts. Meets the strictest password policies for banking, enterprise, and government systems.
Meeting Enterprise Password Policies
Corporate IT policies often require passwords with specific complexity rules: minimum length, mandatory uppercase, mandatory digit, mandatory symbol, and no more than two consecutive identical characters. This generator satisfies all of these requirements by default, and you can customize the rules to match any policy.
Frequently Asked Questions
A 20-character password using the full character set (upper, lower, digits, symbols) has approximately 130 bits of entropy. At current computing speeds, brute-forcing such a password would take billions of years, even with specialized hardware.
Most modern services do. A few legacy systems have maximum length limits (often 16 or 20 characters) or disallow certain symbols. If a service rejects the password, reduce the length or toggle off specific symbol characters in the settings.
Current NIST guidelines (SP 800-63B) recommend against periodic password changes unless there is evidence of compromise. A truly strong, unique password does not need regular rotation. Focus on using unique passwords per account and enabling two-factor authentication instead.
