Key Connect is a secure, private password manager that keeps your logins and secret notes locked behind Face ID — entirely on your device. Your vault stores two types of entries: logins (website, username, and password) and secure notes (freeform private text). Everything is encrypted in the iOS Keychain, so your secrets never leave your phone. BUILT-IN PASSWORD GENERATOR Stop reusing weak passwords. Key Connect's generator creates strong random passwords or memorable passphrases in seconds. Choose your length, toggle uppercase, digits, and symbols, or switch to passphrase mode for something you can actually remember. Copy to clipboard with one tap — and it auto-clears after 30 seconds. PASSWORD HEALTH AUDIT The Health tab scans your entire vault and gives you an overall score out of 100. It flags: - Weak passwords that don't meet strength criteria - Reused passwords shared across multiple accounts - Old passwords that haven't been changed in over a year Tap any flagged entry to jump straight to editing it. CATEGORIES AND FAVORITES Organize entries into custom categories with icons and color-coded chips. Star your most-used logins to find them instantly in the Favorites tab. FAST, FOCUSED, PRIVATE No account required. No cloud sync. No ads. Key Connect is a single-purpose tool designed to do one thing well: protect your passwords and keep them at your fingertips.
