Passwords and passphrases
A long random password is hard to guess and hard to type. A passphrase made of several unrelated words is easier to type and still gives you a lot of guessing room. Pick the one you will actually use.
What the strength label means
The label estimates how much guessing the value would take, based on its length and the character sets you selected. It is a rough guide, not a guarantee, and it says nothing about whether a service will store your password properly.
Storing what you generate
Put the value in a password manager rather than a note or a chat message. If you need to send one to someone, the one-time secret tool on this site keeps it to a single read.
How it works
Generate on this device
The browser uses its cryptographic random source. The result is not requested from the server.
Save it safely
Copy the result into a password manager. Reloading the page discards the generated value.
Is anything sent to the server?
No. The value is built in the page from the browser's cryptographic random source. There is no request while you generate, so nothing appears in a server log.
Should I use a password or a passphrase?
Use whichever you can type accurately on the device in front of you. A five-word passphrase is long enough for most accounts, and a twenty-character random password is stronger still if you are pasting it from a manager.
Can I generate the same value twice?
Not on purpose. Each run draws fresh randomness, so a reload gives you a different value. Save the one you keep.
