Conceal Authenticator vs Phasm

Conceal Authenticator redefines two‑factor authentication with true decentralization and military‑grade encryption. It’s the world’s first 2FA app that securely backs up your keys directly to the blockchain — no registration, no central servers, no single point of failure. Use Conceal Authenticator just like any standard 2FA app — scan your favorite services’ QR codes to generate secure TOTP codes — and take advantage of our built‑in, decentralized backup options. Recover using your Conceal wallet seed: simple, private, and under your full control. Key Features: Handles by default TOTP SHA1, 6digits, 30 seconds, and also SHA256, SHA512, 7,8 digits, and 60seconds. Local‑only mode — for those who wants to give it a try, before upgrading to blockchain backup. Decentralized blockchain backup — Your keys are stored securely and optionally automatically. Biometric security — Unlock with fingerprint, face recognition or password. Multiple themes, QR scanning, and Future code previews. Share access securely — Whitelist trusted contacts for encrypted 2FA sharing. Built‑in wallet — Access and recover with your Conceal wallet seed. Cost of a transaction (backup entry or permanently deletion) is 0.0111CCX per key. Whether you’re a privacy advocate, crypto user, or security‑minded individual, Conceal Authenticator offers a next‑generation approach to 2FA — decentralized, self‑custodial, and unstoppable. Note: To enable blockchain backup, a small amount of Conceal Network coins (CCX) is required. You can ask friends or family for some, or join the Conceal Network community to get started. ALWAYS MAKE SURE YOU BACKUP YOUR SEED PHRASE WITH CREATION HEIGHT or EXPORT QR CODE, so you can regenerate your wallet and recover you 2FA keys when migrating to a new phone. Powered by the Conceal Network blockchain.

Hidden in plain sight. Phasm turns ordinary photos into secret messengers. Your photo looks exactly the same — but it carries encrypted messages and files that only someone with the right passphrase can reveal. TWO MODES FOR TWO NEEDS • Ghost Mode — Maximum stealth. Advanced adaptive algorithms make hidden data virtually undetectable, even by statistical analysis tools. Deep Cover auto-activates for non-JPEG photos with ~43% more capacity. Supports file attachments alongside your message. • Armor Mode — Maximum durability. Your hidden message survives recompression, re-encoding, and mild cropping. Fortress sub-mode auto-activates for short messages and handles aggressive compression from popular messaging apps. SERIOUS ENCRYPTION • AES-256-GCM-SIV authenticated encryption — always on, not optional. • Argon2id key derivation — resistant to brute-force and GPU attacks. • Post-quantum safe — 256-bit symmetric keys remain secure against quantum computers. • No backdoors. No key escrow. You hold the only key. PRIVACY BY DESIGN • All processing happens on your device. Nothing is uploaded. • No account. No sign-up. No tracking. No ads. • Open-source Rust cryptographic engine — auditable by anyone. • Built for journalists, researchers, activists, curious tinkerers — or just for fun. ONE PHOTO. MULTIPLE SECRETS. Shadow Messages let you hide several independent messages in a single photo — each locked with its own passphrase. Send the same picture to five friends; each one discovers a different message using their name as the key. Nobody knows the others exist. Under pressure to reveal your passphrase? Hand over the primary one. Your shadow messages stay invisible — no header, no marker, no proof they were ever there. MAGIC WAND — ONE TAP TO OPTIMIZE Tap the wand and your photo is silently tuned for better steganographic embedding. Imperceptible texture is added to smooth regions like skies, bokeh, and flat backgrounds — boosting capacity by 10–35% with no visible change. The photo looks identical. The math works better. SHARE YOUR WAY • Share via AirDrop, Messages, email, or any app that handles images. • phasm.link — generate a short link so recipients can decode instantly in the browser or via App Clip. No install needed. • For guaranteed delivery through messaging apps, use "send as file." BUILT FOR iPHONE AND iPAD • Native app optimized for iPhone and iPad. • Supports JPEG, PNG, GIF, WebP, and HEIC — auto-converted for embedding. • Real-time decode progress with integrity scoring. • 38 languages supported. HONEST ABOUT LIMITATIONS • Platforms that resize or re-encode photos may destroy hidden data. Use direct sharing or "send as file." • Capacity depends on image resolution — larger photos carry more data. • Steganography hides the existence of a message. Encryption protects its content. Phasm gives you both.
