Alphanumeric only · 06

No symbols accepted? Add length, not predictability.

Create an alphanumeric password for legacy systems, recovery codes, and forms that reject punctuation. A longer default compensates for the smaller character pool.

Local

No generation request

Every selection happens inside this browser tab. The server only delivered the page.

Temporary

No saved history

Results are never written to cookies, local storage, session storage, or a database.

Unbiased

Fair random selection

Rejection sampling removes modulo bias before values are mapped to characters or words.

A password can be strong without punctuation.

Symbols expand the pool of possible characters, but length multiplies the number of possible combinations. A sufficiently long, uniformly random alphanumeric password remains highly resistant to brute force.

Practical advice: When symbols are unavailable, use all alphanumeric sets and at least 20 random characters.

Compatibility is a valid requirement

Older databases, embedded devices, airline systems, and command-line tools sometimes reject punctuation. Generate for the actual policy instead of manually deleting symbols.

Do not replace symbols with a pattern

Appending a predictable year or sequence does not restore meaningful randomness. Let the generator select every character.

Store the result safely

An alphanumeric password is still difficult to remember. Save it in a password manager and avoid sending it through email or chat.

Before you use the result.

Are passwords without symbols secure?

Yes, when they are long, random, and unique. Symbols are helpful but not mandatory for a strong generated password.

Why is the default 24 characters?

The longer default provides extra margin for the reduced 62-character pool and remains compatible with many systems.

Can I use lowercase only?

A lowercase-only password can be secure if sufficiently long and random, but this tool uses all alphanumeric sets for better efficiency.
