A password generator app is doing its job only when the password is hard to guess and also legal on the form in front of you. Invented passwords fail the first test. Many generators fail the second: the site rejects the result, and you weaken a good string by deleting characters until the form stops complaining. PasswordMe is a strong password generator for iPhone and iPad that takes the form's rules as the input. It is not a password manager. PasswordMe does not autofill passwords. Not saved unless you turn on encrypted history.
Set the length the form allows
Length does more than a clever substitution. Every added random character multiplies the guesses required, and PasswordMe can build anything from 4 to 256 characters. When a password manager will type it for you, pick a length past the site's minimum. When a legacy payroll or banking screen still caps you at 8, that cap is the problem to solve. Generate at the length the form allows. Do not make a longer password and chop it down by hand.
Match the character rules
Enter the mix as exact counts for uppercase letters, lowercase letters, numbers, and symbols. If the page wants two uppercase letters, three digits, and two symbols, say so. Then restrict symbols to the set that site accepts. Braces, slashes, and quotes are common rejects, and a rejected password helps no one. When a person will read the password aloud or type it from a card, strip look-alike characters too: zero and O, and one, l, and I. Those pairs cause lockouts, not extra strength.
Control the first and last character, for example requiring a letter when a form rejects a leading number or symbol. Ban repeated characters, alphabet runs such as abc, and keyboard walks such as qwerty. If two rules cannot both be true, PasswordMe tells you before it generates, instead of returning a password that quietly dropped a rule. The home page lists those controls in shorter form.
Generate it on the device
The generator on this page runs in your browser and does not send the password or your rules anywhere. PasswordMe generates on the iPhone or iPad, using the cryptographically secure random number generator built into the operating system, and it keeps working with Wi-Fi and cellular turned off. There is no account and no sync. Passwords are excluded from analytics, logs, and ad requests. The app is free because it shows ads, so it does use the network. The secret is not part of that traffic. PasswordMe Pro removes the ads. The privacy policy states the same limits in full.
A preset stores the recipe for a fussy form: the length, the counts, the approved symbols, the ban on repeats. It does not store the password that recipe produced. Open it later and you get a new secret that still passes the same screen. Optional history is off unless you turn it on. When it is on, it stays on the device, encrypted at rest, behind Face ID or Touch ID. A copied password expires from the clipboard, and the app hides its screen in the app switcher.
Use one password per account
A strong password reused everywhere is only as safe as the worst site that stored it. Give each account its own. When you are opening several accounts, generate a bulk batch of unique results instead of tweaking one string. If the secret has to be read aloud or tapped into a television, use a passphrase or a pronounceable password, which is built to be said without spelling every letter. If the field accepts only digits, use a pattern-checked PIN. For a home network, use a Wi-Fi password that is long enough to say out loud and free of look-alike characters.
