No Special Characters Password Generator

A no-special-characters password generator creates passwords using only uppercase letters, lowercase letters, and numbers — without symbols like !@#$%. This is the go-to solution when a site or system rejects passwords containing special characters. Cryptographically generated in your browser.

    🔒 Passwords are generated in your browser and never transmitted to any server.

    Why some systems reject special characters

    Some platforms have arbitrary restrictions on which characters a password can contain. Common reasons include: legacy authentication code that breaks on certain characters, databases that improperly escape inputs, customer service systems designed for phone dictation, and older enterprise software. These restrictions are a security red flag in new systems, but they're a reality with legacy platforms.

    Compensating for removed symbols

    Removing symbols shrinks the character pool from 94 to 62. The entropy cost is about 0.6 bits per character. Compensate by using more characters — a 18-character no-symbol password (~107 bits) matches the entropy of a 16-character full-charset password (~105 bits). Always push for the maximum length the system allows.

    Frequently Asked Questions

    It's usually a legacy system limitation or poorly written input validation. Modern systems should accept all printable ASCII characters. If a site restricts characters, compensate with length — use 18–20 characters instead of 16.

    Yes, if it's long enough. A 16-character alphanumeric password has ~95 bits of entropy — well above the threshold for strong security. The symbol restriction costs about 10 bits, which is compensated by 2 extra characters.

    Use at least 16 characters when symbols aren't allowed. This gives ~95 bits of entropy with uppercase + lowercase + numbers. For important accounts, use 18–20 characters to ensure equivalent strength to a 16-character full-charset password.

    Yes. Password managers like Bitwarden and 1Password let you configure character restrictions per entry — you can generate a no-symbol password and save it automatically. This is the best approach for sites with character restrictions.
