Use a unique password for this account
Reusing a password is how one leak opens the rest. A password manager can store it. Do not recycle a phrase you already typed on another site.
Length 16+. Letters, digits, symbols. Exclude 0 O I l 1 if you will type it. Open password on cv.cm
Generation stays in this tab. Random bytes come from Web Crypto on this device.
Open Password generatorSet length 16 or more
Default is 16. Longer is stronger if the site allows it. Below 12 is for the sites that still cap length, not a goal.
Keep letters, digits, and symbols unless the site forbids them
Exclude similar drops 0, O, I, l, and 1 so you can read it. If a bank form rejects symbols, turn symbols off for that account only.
Copy once and paste into the account
Do not screenshot it. Do not put it in email or chat. A password manager is the place to store it after paste.
Copy once. Paste into one account. Do not email it. Close the tab. Close the tab
Closing discards the password from this page. If you did not store it, generate a new one — do not try to remember a random string.
