that's not good, it may be someone want's to hack your Airbnb account.
Open Airbnb on your laptop, log in, click on your profile picture in the upper right corner/account/ click on the security in your left side menu and you will see your "login history" look there if your account was accessed from an unfamiliar device
On the same page you can change your password.
Click on payout methods and payout preferences on the left menu and check if there is still your bank account number.
Click on transaction history to see if someone booked any accommodation with your credit card
Click on notifications and check if your email and your phone number are still yours. If it is changed and don't belong to you then change it again on your profile page.
