Groups: a Graph-backed picker on the Security tab (search by name or paste object IDs) stores allowed group IDs. During sign-in membership is read from the ID token's groups claim when present, otherwise verified through Microsoft Graph checkMemberGroups (transitive). Verification failures refuse the sign-in. Button-only mode: hides the password form and the lost-password link and rejects password sign-ins on wp-login.php via the authenticate filter. A generated, rate-limited fallback key re-enables the form for 30 minutes per browser; M365_LOGIN_DISABLE_BUTTON_ONLY switches the mode off from wp-config.php. Also: new German-language README with sequence diagram, settings reference, troubleshooting and hook examples; readme.txt external services section now covers Microsoft Graph; translations updated.
