Password Generator Without Special Characters
Generate strong passwords without symbols — letters and numbers only. Ideal for systems that reject special characters. Free, browser-based, no signup.
About this password generator without special characters
Some systems still restrict passwords to letters and numbers only — older enterprise software, legacy banking portals, certain IoT device interfaces, and some government systems reject special characters entirely. While symbol-free passwords have lower entropy per character, you can compensate by increasing length. A 20-character alphanumeric password using uppercase and lowercase letters plus digits has approximately 119 bits of entropy — still effectively uncrackable. This generator defaults to 20 characters with uppercase, lowercase, and numbers enabled, and symbols disabled. If the system requires only letters (no numbers either), increase the length further to at least 24 characters to maintain adequate entropy.
FAQ
Common questions
Why do some sites not allow special characters in passwords?
Usually legacy technical reasons: old databases with character encoding issues, systems that insert passwords into SQL queries without proper parameterization, or input validation written before modern security standards. NIST explicitly recommends that sites accept all printable ASCII characters.
How long should a password be without symbols?
Without symbols, use at least 18-20 characters to maintain strong entropy. With only letters and numbers (62 possible characters), each character contributes about 5.95 bits of entropy. 20 characters gives ~119 bits — still very strong.
Is a password without symbols still secure?
Yes, if it is long enough and truly random. The key word is random — "HelloWorld123" has no symbols but is extremely weak because it follows a predictable pattern. A randomly generated 20-character alphanumeric string is very strong.
Can I use only lowercase letters for a password?
Only if forced to and only with extreme length (30+ characters). Lowercase-only passwords have just 26 possible characters per position (~4.7 bits each), requiring 17+ characters to reach 80 bits of entropy.
What if the site also rejects certain letters?
Some systems reject letters that look like numbers (O, 0, I, l) to avoid confusion. If needed, generate a password and manually replace any ambiguous characters — or increase length to compensate for the reduced character set.
