Passwords should be easy to remember, not easy to guess. PasswordPerfect builds passphrases from real words — the kind you can say out loud, type on a phone keyboard, and actually recall. A string like dancing-dizzy-dragons is friendlier to your memory than Xk9#mQ2v, and far harder for a machine to guess. MAKE IT Tap once for a fresh passphrase. Don't like a word? Swipe it for another, edit it, hide it, or reorder the whole thing. Choose a word pattern — Random Words, Verb • Adjective • Noun, Adjective • Noun, or Color • Creature — and give your passphrase a shape. TUNE IT The Tune Bar keeps case, separators, and word play within thumb's reach. When a site demands a digit, a symbol, or a character limit, Make It Pass lets you place substitutions exactly where you want them, with an honest strength meter that tells you where you really stand. USE IT ANYWHERE • AutoFill: generate and insert right from any password field. • Widgets: Home Screen, Lock Screen, and StandBy. • Control Center: a fresh passphrase one button away. • Shortcuts and Siri: generate a passphrase inside your own automations. • iPad: two-column layouts that use the room. • The clipboard clears itself 60 seconds after you copy. PRIVATE BY CONSTRUCTION Everything happens on your device. PasswordPerfect has no accounts, no cloud, and collects nothing — it generates, you use, that's the whole transaction. Accessible throughout, with full VoiceOver support and respect for Increase Contrast, Reduce Motion, and Reduce Transparency. Light and dark, of course. Handcrafted with love by BluMonkey Software.
