SUBSCRIPTION Protegy offers auto-renewing weekly and yearly subscriptions. Payment is charged to your Apple Account after purchase confirmation. The subscription renews automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel it in your Apple Account settings. Terms: https://specterapps.com/terms/ Privacy: https://specterapps.com/privacy-policy/ Apple Watch: Send selected authenticator accounts from iPhone with Protegy Premium and view verification codes offline on your paired Watch. A Watch passcode and wrist detection are required. Passwords and recovery codes remain on iPhone. Previously transferred codes remain available after Premium expires. Passkeys (iOS 17+): Enable Protegy as a system credential provider to create and use passkeys on compatible websites and apps. Creating new passkeys requires Protegy Premium and explicit opt-in in Protegy. Saved passkey sign-in remains available after Premium expires. Optional passkey sync is off by default on each device and affects only future creations. New eligible keys can sync through iCloud Keychain between iPhone and iPad using the same Apple Account, with iCloud Keychain enabled on both. Delivery may take time; saving a key does not confirm delivery. Existing device-only keys remain local and cannot be converted. Sync-eligible keys use iCloud Keychain protection and app-enforced device authentication for each use. Protegy does not import or export passkeys or provide passkey features on Apple Watch. Removing the device passcode permanently deletes legacy device-only keys. Keep another website sign-in method.

Prove you're real. Stamp anything. Verify anyone. RealStamp is a human authenticity system — a cryptographic toolkit that lets you sign any piece of content with proof that a verified human attested it. Locked to your Face ID. Anchored on a public transparency log. Verifiable by anyone in seconds. HOW IT WORKS STAMP. Capture text, attach a photo, video, or file. RealStamp signs it inside the Secure Enclave on your iPhone, with a key that never leaves the chip. Every stamp anchors to Sigstore Rekor — a public, append-only transparency log. Patent pending. SCORE. A 0–100 Trust Score reflects how verifiable you are and your stamping track record — never whether you used AI. It's built from your verified identity (email, phone, social, ID), your stamping activity (volume and consistency over time), and the quality of your credentials (taking editorial responsibility, maintaining the C2PA chain, and keeping stamps active). Open disputes and revocations reduce your score. VERIFY. Anyone, with or without an account, can verify any RealStamp credential in seconds. Signature, anchor, score, and dispute status — all public, all auditable. WHAT'S INSIDE • Hardware-backed Face ID — every stamp signed by a key inside Secure Enclave. FIDO2 Level 3 equivalent. No password. No software fallback. • Sigstore Rekor anchoring — every credential written to a public transparency log. Cannot be backdated or forged. • SD-JWT credentials — selective disclosure. Show what you want, prove the rest. • Sign in with Apple supported — when you choose Apple's Hide My Email, your real address is never shared. • C2PA-compatible content credentials — built on the open C2PA standard for content provenance. WHO IT'S FOR Creators publishing original work. Journalists and witnesses in the field. Researchers and authors. Anyone who wants to be verifiable as human in a synthetic world. PRIVACY Signing happens inside the Secure Enclave on your device. Liveness frames are processed in real time and discarded — we do not store any biometric template or faceprint. Photos and videos you choose to attach to a stamp are stored so verifiers can see what was stamped; you can delete them at any time. We support Sign in with Apple, email with a 6-digit code, and device passkeys. REGULATORY Designed to meet EU AI Act Article 50 disclosure requirements. Patent pending (USPTO 64/045,301). FREE TO DOWNLOAD. FREE TO VERIFY OTHERS. No account needed unless you want to stamp content yourself. realstamp.app LEGAL Privacy Policy: https://realstamp.app/privacy Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Verdict
The clearest difference is rating: RealStamp at 5.0 against Authenticator App's 4.3. RealStamp also leads on ads (none vs shown) and monetization model (free vs free with in-app purchases). Authenticator App's advantage is ratings volume (9 vs 1). On price, update cadence, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Authenticator App sells 4 in-app purchases, starting at $4.99 per 7 days and RealStamp sells 4 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
RealStamp holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Authenticator App has 9 ratings behind it against 1, so its average is the more settled of the two.
Authenticator App ships an update fortnightly, RealStamp every 2 weeks. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
