If your phone is lost, stolen, or you think someone else has accessed your account, you can sign InterChat out on every other device without needing that phone in hand.
- On a device you still control, open InterChat.
- Go to Settings → Where you're signed in.
- Find the device you want to sign out and remove it.
For good measure, also change your password straight after (see I forgot my password, which works the same way even if you haven't forgotten it — just choose a new one).
If you believe someone else has actually accessed your account, tell us at support@interchathq.com as well, so we can help keep it secure.
