Your cards, close at hand. Scan both sides, find saved copies offline, and choose which details to show. PRIVATE BY DEFAULT Your wallet is encrypted on your iPhone and protected by device authentication. Text recognition runs on-device. Core wallet use needs no digiID account. Cover sensitive details, save Ways to Present, and open a focused presentation. START FREE Keep one card free, with basic privacy editing, code checks, recovery and plain privacy-masked PDF export. Review scans and suggested masks: detection can miss details. TRAVEL & EMERGENCY PACKS Choose cards, sides and order for a trip or personal emergency pack. Review missing cards, changed pictures and expiry warnings before exporting. Preview is free; Plus saves reusable packs and exports reviewed pack PDFs. Packs require normal device unlock and are not emergency-responder access. LEARN DIGIID An optional quick start, short lessons and safe sample practice help you find your way. Reopen Learn digiID whenever you need it. OPTIONAL SECURE LINKS From a reviewed disclosure, choose Share securely and an expiry from 10 minutes to seven days. Only the selected pictures are encrypted before upload. The key stays in the private link fragment, separate from the sharing server. Recipients can view the copy in a browser or supported App Clip without a digiID account. Check the first-view receipt or revoke the link. Expiry and revocation block later retrieval; they cannot erase copies someone already saved. APPLE WALLET WITH PLUS Create pictured personal references from any category, or copies of compatible static membership codes. Review the masked front and optional back detail. Personal references need no typed code. Apple confirms Add to Wallet. With consent, reviewed pass fields, image fingerprints and Apple subscription proof go to the signing service. Wallet pictures are attached on your iPhone. Wallet keeps a separate copy outside digiID's lock; later edits and Plus expiry do not update or remove that copy. Use Present card in Pass Details to open the saved presentation after authentication. Apple controls other pass taps. Official IDs, payments, changing codes and NFC keys require issuer support. Import an issuer's original .pkpass when available. QUICK ACCESS Named shortcuts use an automatically cropped picture and 14 frame choices. Apple confirms Home Screen installation. Widgets and shortcuts open the matching presentation after authentication. Their exported names and pictures are outside digiID's lock and may sync through Apple. Add an expiry event to your calendar with 30-, 7- and 1-day reminders after granting permission. DIGIID PLUS Plus adds more cards, reusable packs, reviewed pack PDFs, Wallet creation, shortcuts, widgets, more saved presentations, decorative privacy finishes and PDF purpose labels. The U.S. offer is a three-day free trial for eligible subscribers, then $3.99/month. Apple shows local prices and eligibility. Payment is charged to your Apple Account. Plus renews automatically unless canceled; manage it in Apple Account subscription settings. EXISTING PURCHASES & NITO Original Unlimited Cards retains its purchased capacity. Restore using the purchasing Apple Account. Ending Plus does not delete saved cards or masks. NITO is a separate one-time encrypted-vault purchase requiring original Unlimited. Store photos/PDFs locally and make manual encrypted backups. Recovery needs the backup and separate recovery key. No NITO cloud sync is included. digiID stores personal copies, not issuer-verified identification. Decorative privacy effects are not issuer security marks. Update without deleting the app to preserve older cards available for recovery. Privacy: https://digiid.com/privacy/ Terms: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

About

Otter 2FA Authenticator

Features
Read full description

Otter generates your two-factor authentication codes on your phone, from keys that stay on your phone. No account. No cloud. No server. Nothing to create, no extra password, nothing to confirm by email. Otter makes no network requests at all, and it cannot replace its own code after you install it. What you install is what runs. MOVING IN, AND MOVING ON - Reads the standard otpauth setup codes any other authenticator can export - Exports one encrypted backup file, sealed with a passphrase you choose - Import adds to what you have, or replaces it, and tells you which before it acts - The backup holds standard URIs, so it stays readable elsewhere if you ever leave WHAT IT DOES - Adds accounts by scanning a QR code, or by typing the key by hand - Generates standard TOTP and HOTP codes, as used by every major service - Groups the digits 3+3 and shows the seconds left, so nothing jumps as it changes - Copies a code with one tap, and clears the clipboard afterwards - Hides codes until you tap them, and can block screenshots HOW YOUR KEYS ARE KEPT - Every key is encrypted with AES-256-GCM before it touches the disk - The key that opens them is held by your phone's own secure hardware, behind Face ID, Touch ID or a PIN - A wrong PIN slows down the next attempt, and the delay survives a restart - Otter shows codes, never the keys behind them THE REST - Free. No adverts, no subscription, no in-app purchase, no paid tier - English and French, following whichever your phone is set to - Ten app icons, and a true black dark mode for OLED screens - No analytics, no crash reporting, no telemetry of any kind WHAT IT PROTECTS YOU AGAINST - A lost or stolen phone, locked - Someone picking up your phone while it is unlocked - Someone reading the app's data directory, or an unencrypted device backup - Screenshots and shoulder-surfing - A leaked backup file, without its passphrase - Silent tampering with the stored data WHAT IT CANNOT PROTECT YOU AGAINST - A rooted or jailbroken phone, or its memory read while the vault is open - A compromised operating system, or a compromised keyboard - Someone coercing you into unlocking it - A PIN or a backup passphrase that is easy to guess And the backup is the only way back. If you lose your phone without one, the keys are gone: Otter holds no copy, so there is nothing on our side to restore from. Export one on the day you install.
