Nydia: Passkey Holder

Passkey storage on the Sia network. Hold your passkeys locally with decentralized backup.

Create and use passkeys in Chrome. Keep them encrypted on your device and back them up to the Sia network. CREATE AND USE PASSKEYS Create passkeys and sign in to websites directly in Chrome. View and manage your saved passkeys from Nydia’s toolbar menu. ENCRYPTED ON YOUR DEVICE Nydia is local-first: your passkeys are encrypted with keys derived from your recovery phrase. No Nydia account required. No telemetry. No tracking. BACK UP TO SIA Back up your passkeys through a renterd server you run and control. Your passkeys are encrypted on your device before upload, so storage providers can’t read them. A backup lets you recover your passkeys if you lose your device. RECOVER YOUR PASSKEYS Start with a new 12-word recovery phrase or enter your existing Nydia phrase. To restore a backup, you need your phrase and access to the renterd server and bucket where the backup is stored. Your recovery phrase alone doesn’t contain your passkeys.
