We're still building this one. We'd rather not ship it until it works reliably end-to-end — no fake progress bars, no pretend success screens.

Strong passwords, the right way
Password security is mostly about two things: length and uniqueness. Length, because each additional character exponentially increases the brute-force difficulty — a 12-character password is 70 times harder to brute-force than an 11-character one. Uniqueness, because reusing passwords means a single breach (which happens constantly) compromises every account using that password.
The right way to manage passwords is with a password manager (Bitwarden, 1Password, KeePass) that generates and stores unique passwords for every account. The password manager remembers the passwords; you remember one master password. Every account gets a unique, long, randomly-generated password, and you never have to type any of them. This is dramatically more secure than any human-memorable password scheme.
If you must memorize a password (your master password, or for accounts you can't put in a manager), the best approach is a passphrase: four or five random common words strung together (correct-horse-battery-staple). That's a 28+ character password that's easy to remember, easy to type, and has more entropy than an 8-character random password with symbols. The xkcd comic on this is still correct.
