We are still working on the grid but signups seem to work now. More bits to translate and make accessible.
Sign in with Session Messenger: open your Session Messenger app and send using qr code or enter the public key. Send the 8-digit passcode to create an account or login.
Sign in with passkeys. Use hardware key such as YubiKey, etc, or platform TPM based such as Windows Hello, or hybrid using mobile device over BLE.
uses Discoverable Credential Authentication with resident keys for enhanced privacy - no key enumeration.
I haven't tested platform/hybrid yet will get to that tomorrow.
Sign in with email. No password, use a authenticator such as Bitwarden (open source)
With your account you get a Wireguard keypair for encrypted tunnel to grid.
Have fun.
