rootcard Key tool
Key tool

Everything that needs your recovery card.

Create an identity, put it on a host or move it, reset or add a password, rotate the recovery key, or close the identity. The page runs entirely in your browser. It contacts no one until you enter a host address, and then only that host.

Only enter your recovery key here, never in an application or a website. Save this page and open it from your own disk.

The .card.json file you saved when the identity was created.
No file? Type the card instead
An .account.json export. It holds the newest log and a copy of your vault, so the tool can work from it even when the host cannot be reached.
The address of the server where you use the identity. A card alone does not know where the identity lives, so enter the host here or load the account file. Leave it empty to work only with the files.
