Hello @Tim100,
Yes this Lithium app should be better signalled by Airbnb. They should at least put an explanation beside the entry to say why it's there.
It allows use of this community forum. After deleting it and then using this forum you'll find that it's there again.
Another one you may see there is SchoolKeep. This shows if you've watched any of Airbnb's information videos.
Yes' it's true that they don't have text or call verification at each login.
They do haave the following things you can do to help secure your account.
Click on your profile photo and then select "Account settings" and "notifications". Under "Push notifications" you should see a box to tick if you want notifications about account activity.
If you click on "Account settings" and then "Security" you'll see a box to click if you want notifications when someone logs in to your account from a different machine or browser.
That page also shows current logins and log in history.
