Strength: very strong. Made on this device and sent nowhere; lookalikes such as l, I, 1, O and 0 are left out.

What this tool is for
This makes a password that nothing can guess, because nothing chose it but chance. Passwords people invent follow patterns, and reusing one means a single leak anywhere opens everything else. A generated password fixes both, provided you keep it somewhere rather than trying to remember it.
How to make a strong password
- Choose how long it should be. Longer matters more than anything else.
- Pick which kinds of characters to include.
- Copy the password and save it in your password manager.
Questions
How long should a password be?
Sixteen characters or more for anything that matters. Length defeats guessing far more effectively than adding another odd symbol does.
How is this random enough to trust?
It draws on the cryptographic random generator built into your browser, which is the same source used for real security work, not a simple shuffle.
I cannot remember something like this. What do I do?
Do not try. Keep it in a password manager and remember one strong phrase that opens that instead. If you want something memorable, the passphrase tool makes words rather than characters.
Does the password get sent or recorded anywhere?
No. It is made in this browser tab, it is never transmitted, and closing the page is the end of it.
