Some systems reject special characters in passwords — legacy apps, certain APIs, Wi-Fi routers, and embedded devices. Generate strong alphanumeric-only passwords (A-Z, a-z, 0-9) that are still highly secure when sufficiently long.
Legacy enterprise systems, API keys, database passwords, Wi-Fi keys, and services that break with special characters all need symbol-free passwords. Compensate by using more characters.

How to Password Generator Without Symbols — Alphanumeric Only
- Open the Password Generator tool
- Enable uppercase letters, lowercase letters, and numbers
- Disable symbols/special characters
- Set length to 16+ characters (compensates for smaller character set)
- Click "Generate Password"
- Copy and use — no encoding or escaping issues
Pro Tips
- 16 alphanumeric chars = ~95 bits of entropy (very strong)
- Use 20+ chars for critical systems that reject symbols
- Alphanumeric passwords never cause URL-encoding or SQL escaping issues
- Still never use dictionary words — randomness matters more than character types
Frequently Asked Questions
Are passwords without symbols still secure?
Yes, if long enough. 62 possible characters (A-Z, a-z, 0-9) at 16 length = 62^16 = ~9.2 × 10^28 combinations. That is extremely strong. Add 2-3 extra characters to compensate for no symbols.
Why do some systems reject symbols?
Legacy systems may use passwords in SQL queries, URLs, or shell commands where symbols cause parsing issues. Some were built before proper escaping was standard practice.
How many characters without symbols equals one with symbols?
Roughly: 16 alphanumeric chars ≈ 14 chars with full symbols. The entropy difference is small — length matters more than character variety above 12 chars.
Should I use this for all my passwords?
Only when the system requires it. When symbols are allowed, include them — they add entropy per character, letting you use shorter passwords for the same security.
