This is not a scam. It's a legit monitoring company. I use them to monitor several properties I have in Alabama. They ask for your password in the event there is an alarm so they can verify they are really talking to you and not just some random thief picking up the phone while robbing your home.
Called and knew my name and address. Claimed my home alarm was going off and the police were on the way. Wanted to know my password. They sounded convincing but something hinted that it was a scam.
Have you notified the alarm company and your local police about this call ?
Your alarm monitoring company should have given you the numbers they will call from for alarm notification, but that won't stop criminals from spoofing that number.
"Called and knew my name and address."
When I worked at an alarm-monitoring business many decades ago, whenever I called a customer's residence about an alarm, I never told the customer what their address was. No need to; the customer knew darn well what their address was.
I also never asked the customer for their "password" - we all waited for the customer to provide it. If the customer did not provide it, then we usually considered it a panic situation, and had procedures for that. We also never asked for the passcode to the alarm itself, as the customer can change those themselves at any time; we could never keep up with that.
