OneMoreSecret

OneMoreSecret is a decentralized secrets manager that leverages your smartphone's hardware keystore and biometric authentication to protect your passwords. Instead of relying on a cloud database, your sensitive data (e.g. passwords, TOTP tokens, files, and Bitcoin private keys are encrypted into QR codes or text payloads that can be safely embedded anywhere — even on a public wiki or plain text file.

When you need to use a secret, you simply scan the code or tap the link with your phone, authenticate with your fingerprint to decrypt it locally, and the app acts as a virtual Bluetooth keyboard to instantly "auto-type" the password into your computer. This creates a seamless, air-gapped bridge that keeps your private keys entirely offline, protecting your credentials from keyloggers and cloud breaches while making cross-device authentication completely effortless.
