Connect Administrator ownership to the right LOOM identity.
This is the one-time ownership path for a new LOOM installation. First choose the correct LOOM user on this browser. Then explicitly claim Administrator access. If that identity is already signed into a permanent LOOM account, the Admin role is linked to that account immediately. If it is still a guest, you can make it permanent here afterward.
Make this identity the first LOOM Administrator.
The selected identity will gain protected Admin controls for projects, modules, users, storage and other installation-wide settings. LOOM never performs this claim silently.
If this is a clean migration, choose the portable User or Guest ZIP exported from the previous installation with the SYSTEM OWNER badge. LOOM restores that complete person and binds this browser as the new installation's System Owner using a fresh Admin secret.
Make this Admin account permanent.
This step is recommended. The email/password account will inherit the Administrator role because it is being created from the already-authorized bootstrap identity.
Administrator access is active.
This identity can now open the protected LOOM Admin console.
This identity is not the current Administrator.
Switch to the LOOM identity/account that owns Admin access. LOOM will not transfer Administrator authority merely because this setup page was opened.
