Yes, you got to be careful

At the very least, get your bank to put a transaction alert on your account.

They can clean out your account.

You should be okay as long as you didn't give them your username and password. Routing numbers and account numbers are easily obtainable every time you write a check - both are on the bottom of the check. So there was no harm done there. HOWEVER, 😆 if you get the opportunity to obtain THEIR routing and account numbers, you can cause them some serious problems. It happened to me recently - I was informed that I'd won $3.5 million in the Reader's Digest Sweepstakes. All I had to do was pay the $5000 processing fee up-front. I knew it was a scam, of course. But the guy sent me to a web page that gave his routing and account number (again, not dangerous in itself - that information is used every day). But I found out that you can locate the bank on the web by doing a search on the routing number. Once I found out the name of the bank, I used a link on their site to report a fraud - I gave them the account number. The guy called back the next day to give me a new bank account number to where I could send the processing fee - because something happened to the account he'd given me the day before. I told him that I could help him with that - I told him that I reported him to his bank and they shut his account down. He wasn't a happy camper, to say the least. I thought about it later and realized that not only did the bank shut his account down, but they also seized all of the assets in it. 🤣 There's no telling how much he had in that account from doing this scam - he may have lost hundreds of thousands of dollars! 🤣🤣🤣 I WAS KARMA THAT DAY.
