Some older systems and forms reject symbol characters entirely. This mode defaults to letters and numbers only, so every password it produces is guaranteed compatible.

Tips

Increase length to compensate for fewer character types

Without symbols, each character carries slightly less entropy — consider a longer length to make up the difference.

Confirm the target system's actual rules first

Some systems described as 'alphanumeric only' actually do accept certain symbols — check before assuming you need this stricter mode.

Re-enable symbols if you're unsure

If in doubt, try generating with symbols on first — only switch to alphanumeric-only if the system specifically rejects it.

Frequently asked questions

Why would a system not allow symbols?

Older or poorly-designed systems sometimes have incomplete input validation for special characters — alphanumeric-only avoids the issue entirely.

Is an alphanumeric password weaker than one with symbols?

Per character, slightly — but a longer alphanumeric password can still reach very high entropy. Length matters more than character variety.

Can I exclude ambiguous characters too?

Yes — toggle 'exclude ambiguous characters' to also remove easily-confused characters like 1, l, I, O, and 0.
