I recently gave out my cell phone number on the buy, sell & trade app Offerup to someone, but now I’m concerned that it may be used to steal my identity.
I’ve read in the passed that it’s possible for people to steal your cell phone number and use it to hack into your personal accounts disguised as you to steal your identity.
Currently most of my important accounts have strong passwords and I’m not sure how they would be able to use my number to find the association between it and my bank account, email, etc.
Today there was a suspicious log in on my Instagram account, and it now has me paranoid about the fact that I gave out my number to someone who I believe was likely a scammer.
What should I do in this situation?
