Where to find it

Preferences → Accounts → your account → Login Protection (MITM)

This additional protection helps prevent a sign-in being relayed over another connection. Technically, this is called channel binding. It protects this account’s sign-in; OMEMO and OpenPGP protect your messages.

Server Support shows this account’s result: a green check for available support, a red cross for missing support. Not yet checked is not a confirmed no. Current Connection states whether protection is actually active for the present sign-in.

What to do

Read server support. If unknown or outdated, choose Check Now. Only this account reconnects.
Choose the desired mode. DinoX checks the choice and automatically reconnects the account after a change.
Read the result and Current Connection. An unavailable protection feature cannot be treated as successfully enabled.

What do the choices mean?

Use when available

Uses additional protection for supported sign-ins. This is the default for newly configured accounts. The choice appears after support is confirmed.

This account may sign in only with additional protection. If support later disappears, sign-in is refused. A recovery action deliberately relaxes this requirement.

PLAIN password authentication

A separate advanced-account exception for servers without SCRAM. The password travels inside the TLS connection. Off by default; once SCRAM is confirmed, PLAIN stays blocked. Do not enable it for unrelated sign-in failures.
