This is happening in Production & Trial. A login prompt is popping up in the tenant portal at least once during a reservation and at least twice during a move-in.

Additionally, I was able to use the forgot password feature to execute the forgot password process and received an email with a link to create a new password, which I was able to follow through with and log into my tenant account. The email address I used did not have a tenant account prior to this.

(Not sure if this is a bug, but I was just curious to see what would happen.)

Please see videos linked below for each scenario:
