Phasm vs 2FA Authenticator

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.

Secure your accounts with Autheris — a privacy-first two-factor authentication (2FA) app for iPhone, iPad, Mac and Apple Watch. Autheris generates the time-based one-time passwords (TOTP) that protect your most important accounts, and keeps the secrets behind them on your device. No account, no sign-up, no ads. NOW ON APPLE WATCH • One Code at a Time — Your codes on your wrist, each with a live countdown. Turn the Digital Crown to move between them. • Read-Only by Design — There is no copy, no editing and no settings on the watch. Your iPhone stays the one place codes are managed. • Works Without Your iPhone — Codes are generated on the watch itself, so they keep counting down with your phone out of reach or switched off. KEY FEATURES • One-Tap Codes — Copy a code with a single tap. The clipboard clears itself after 60 seconds. • Pin and Reorder — Pin the codes you use most to the top, and drag the rest into whatever order suits you. • Recently Deleted — Delete a code by mistake? It stays on your device for 7 days, ready to restore. • QR Scanning — Add an account by scanning a QR code, or choose a screenshot from your photo library. • Time-Based and Counter-Based Codes — TOTP for almost every service, and HOTP for the ones that hand you a counter instead, each with SHA-1, SHA-256 or SHA-512 and 6 to 10 digits. If a service rejects your codes, the algorithm is editable per account. • Import — Bring your token generator accounts across from Google Authenticator, Aegis, andOTP or 2FAS. • Search — Find any account instantly, however long your list gets. • Issuer Icons — Familiar brand marks so you can spot an account at a glance. • Countdown Ring — A clear, colour-customisable ring shows how long each verification code has left. PRIVACY AND SECURITY • Face ID / Touch ID Lock — Locks when opened, and again after 30 seconds away. • Blurred When Backgrounded — Content blurs when you switch apps, and your codes are hidden in the app switcher. • Protected While Recording — Codes are covered whenever your screen is being recorded or mirrored. • Secrets Stay on Your Device — Codes and setup keys are kept in your device's Keychain and never leave it unless you export them or turn on iCloud Sync. • Encrypted Backups — Save an AES-256-GCM encrypted backup protected by a password only you know. • Optional iCloud Sync — Off by default. When you enable it, your secrets are end-to-end encrypted by CloudKit, and the developer cannot read them. • No Account, No Tracking — Nothing to sign up for, no analytics, no advertising. Autheris is open source. Install Autheris, add an account, and keep your second factor — and your 2-step login — under your own control.
