Remote NIP-46 signing is exposed to Nostr web clients through Bunker46, a NIP-07 browser extension.
About Bunker46
Bunker46 Extension is a NIP-07 browser extension that exposes window.nostr to web pages and forwards signing requests to a remote NIP-46 signer over Nostr relays instead of storing private keys in the browser. It connects with a bunker:// URI or nostrconnect QR/URI, and saves the session across restarts.
It provides multiple profiles with separate sessions and permissions, per-domain approvals, an optional privacy whitelist, and settings for a custom Bunker46 instance URL and nostrconnect relays. Chrome and Firefox (MV3) builds are supported.

Bunker46 FAQ
How do I connect the extension to a remote signer?
Connect with a bunker:// URI or nostrconnect; the extension shows a QR code and copyable URI to scan with a bunker app, and saves the session after restart.
How do site permissions work?
Each site must be allowed once or always before using the Nostr identity; domains or individual methods can be revoked from the Permissions tab.
What does disconnecting do?
Disconnect asks for confirmation, then disconnects, clears all permissions, and clears the privacy whitelist for the active profile.
