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.
Create several passwords at once using the settings above — useful for provisioning multiple accounts.
Type any password to score it instantly. This runs entirely in your browser — nothing is sent anywhere, logged, or stored.
Without symbols, each character carries slightly less entropy — consider a longer length to make up the difference.
Some systems described as 'alphanumeric only' actually do accept certain symbols — check before assuming you need this stricter mode.
If in doubt, try generating with symbols on first — only switch to alphanumeric-only if the system specifically rejects it.
Older or poorly-designed systems sometimes have incomplete input validation for special characters — alphanumeric-only avoids the issue entirely.
Per character, slightly — but a longer alphanumeric password can still reach very high entropy. Length matters more than character variety.
Yes — toggle 'exclude ambiguous characters' to also remove easily-confused characters like 1, l, I, O, and 0.
Older banking systems, some government portals, and certain legacy enterprise software are the most common examples still restricting or discouraging symbol characters.
Yes — increasing length is the most effective way to offset the reduced character set, since every extra character multiplies the total number of possible combinations.
No — regardless of character set, reusing predictable patterns across accounts remains risky. Each generated password should be unique per account.
