Authy makes exporting your 2FA secrets deliberately impossible, and 1Password wants $2.99+ a month, about $36 a year, just to hold the same codes in someone else's cloud. Keyloop is a desktop authenticator where you hold the vault: AES-256 encrypted on your own disk, exportable to an encrypted file, a printable QR paper backup, or a standard otpauth:// list. Pay $19 once, and you are never locked out or locked in.

• Live 6-digit codes — Per-account countdown rings and click-to-copy with a clipboard that auto-clears.

• Add accounts three ways — Scan a QR screenshot, paste an otpauth:// URI, or type the secret manually, with SHA1/256/512, 6-8 digits and custom periods.

• Encrypted local vault — scrypt key derivation into AES-256-GCM using Node built-in crypto; the master password is never stored and it auto-locks after five minutes idle.

• Encrypted .keyloop backups — One file, one password, restore anywhere.

• Printable QR paper backup — Every account as a QR code on one sheet for your safe or deposit box, the escape hatch Authy refuses to give you.

• Bulk migration — Paste an otpauth:// URI list from any other authenticator export.

• Zero network — No accounts, no cloud, no telemetry; the app makes no network calls at all.

Runs as a Windows desktop app.
