A passphrase generator makes a password out of words. The result is still random. It is random in a shape a person can say, read, and type without losing their place. PasswordMe does this on iPhone and iPad from English or Spanish word lists, and you choose the separator and the capitalization. A memorable password is easier to handle than a symbol string. It should still not be about you: a lyric or a pet name is easy for someone else to try.
Pick random words, then add more of them
Words the app selects, with no theme tying them together, are the point. Use as many words as the form will take. A phrase built from the app's word list is meant to be said and typed. It is not a substitute for a long random password on an account where guessing matters. A sentence you compose yourself shrinks the number of possibilities, which is the wrong direction. If you will have to spell it under pressure, use the language you can spell. The Spanish list is not a translation of an English phrase. It is a separate draw from Spanish words.
Use the separator for the form, not for the strength
Forms still demand a digit, a capital, or a symbol. Spend the separator and the capitalization on that demand. A hyphen, a space, or one symbol the site allows is enough of a break between words. Capitalizing each word, or only the first, satisfies many uppercase rules without making the phrase harder to read. When a form rejects spaces, change the separator and generate again. Shortening the phrase to squeeze it in is the edit that costs you strength.
Memory Phrase is a cue, not the secret
Memory Phrase takes a cue you supply and wraps it in fresh randomness. The cue helps you recognize the result later. It is not the source of strength. A pet name on its own, or a pet name with a digit, is still a pet name. If you use this mode, keep the random part the app added. Pronounceable passwords sit between a word list and a fully random string: they are built to be said over the phone without spelling every letter, and they are not dictionary words. Use one when a site rejects spaces and long phrases. Use a passphrase when the form will accept the words. A fully random password, with exact character counts, is the better tool when a manager will do the typing. That mode is covered in the password generator guide.
Keep the phrase on the device
A passphrase is a password, even though it looks friendly. Do not mint it on a website. PasswordMe builds it on the device with the operating system's cryptographically secure random number generator, and it still works with Wi-Fi and cellular off. There is no account. The phrase is not sent in analytics, logs, or ad requests. The app shows ads, so it does use the network. The phrase is not included. Copy it into your password manager. PasswordMe does not autofill passwords. Not saved unless you turn on encrypted history. A preset can remember how you like these phrases built, and it stores those rules only, never the phrase. Details are in the privacy policy.
Give important accounts their own phrase. Reusing one memorable password everywhere means a single leaked site reveals the rest. When you must read a secret to someone in the room, a passphrase or a pronounceable password is kinder than a random string, and it is still worth generating on the phone rather than inventing it out loud. If the field takes only digits, use a pattern-checked PIN. If you are setting the home network, make something long, sayable, and free of look-alikes, which is what the Wi-Fi password guide covers.
