Read full description

2FA Authenticator Verification is a secure app for storing and displaying verification codes used to sign in to various online services such as email, social platforms, and work tools. CORE FUNCTIONALITY: QUICK ACCESS TO CODES All connected services are shown in a single list. For each service, the app displays the current six-digit code, a visual timer indicating when the code will refresh, and a copy action. Codes refresh approximately every 30 seconds. Tapping a code copies it to the clipboard and confirms the action with a short message. SIMPLE SERVICE SETUP New services can be added in two ways: โ€ข Scan a QR code provided during account setup โ€ข Enter details manually by specifying the service name and secret key SERVICE MANAGEMENT Any added service can be removed from the list. Deletion always requires confirmation and completely removes the service from the app. APP PROTECTION Access to app can be protected with a PIN code. When enabled, the app locks automatically after being minimized. Available settings include: โ€ข App lock on/off โ€ข Change PIN code CODE VISIBILITY ON LAUNCH You can enable a mode where verification codes are hidden when the app is opened. Codes become visible only after user confirmation, such as unlocking the app or tapping a "Show" button. When this option is disabled, codes are displayed immediately. CLIPBOARD CLEANUP When enabled, copied codes are removed from the clipboard after a short time (30 seconds), without requiring any action from the user. When disabled, copied content remains in the clipboard until it is replaced. FREE AND PREMIUM FREE VERSION - Add up to 5 services - Verification codes are visible immediately when the app is opened - Copied codes remain in the clipboard until replaced - App protection with PIN is available PREMIUM VERSION - Unlimited services - Option to hide verification codes on app launch - Automatic removal of copied codes from the clipboard after a short time - Extended privacy controls 2FA Authenticator Verification is designed for clear, secure, and straightforward management of verification codes.

About

Cairn

Stack before you scroll. Cairn helps you stop scrolling by adding one small pause before distracting apps open. Choose the apps you want to protect. When you reach for one, iOS shows a Screen Time shield. Open Cairn, build the requested stone structure, and earn a short window to continue. It is enough to break the reflex. Often, that is all you needed. What's in Cairn - Stack: balance stones into target structures before the app opens. - Short unlock windows: earn a few intentional minutes, then the shield returns. - Multiple rituals: Stack, Breath, Trace, Walk, and Untie. - Stone styles: granite, basalt, riverstone, obsidian, marble, moss, and moonstone. - Sunday reflection: save a private weekly reflection about the pauses you kept. - Lock Screen widget: see minutes reclaimed today at a glance. Built for focus - Uses Apple's Screen Time controls for app blocking. - No account. - No cloud. - No ads. - Your watched-app list stays on your device. - Haptics, sound, and calm visual design built around one idea: interrupt the reach before it becomes a scroll. Free Cairn includes core blocking and daily stack rituals. Cairn Pro unlocks deeper rituals, stone styles, custom unlock windows, weekly reflection, and more ways to hold the trail. Cairn is not a dashboard for judging your phone use. It is a small threshold between impulse and action.
