Certificate (RFC 7523 client assertion) as an alternative to the client
secret: one-click generation of a 3072-bit RSA key pair with a
self-signed certificate, .cer download (public part only), own PEM
upload with validation, expiry display, encrypted key storage. Both the
authorization code exchange and the Graph client-credentials request
use the selected method. Step-by-step guides for secret, certificate
and the app registration are shown in the settings.
Security audit (docs/security-audit.md) and fixes:
- Multi-tenant mode ignored the unverified email claim: matching now
uses the UPN only, or the email claim when xms_edov is true.
- Login starts are rate limited per client (30 per 10 minutes).
- Optional trusted proxy header for client IPs
(M365_LOGIN_CLIENT_IP_HEADER / filter).
