Instagram account maybe hacked

Got a notification that someone else logged into my insta account and then it said I can change the password to secure my account so I did that and logged out and logged in again with the new password, but I'm still a bit worried they might have access to my account. If I've done the above, does that mean they have been logged out now and can't access my account?

Are you absolutely sure that the e-mail you received was really from Instagram itself? Having read it, did you click on any links/buttons in order to get to Instagram (to change your password)? Do you have two-factor authentication enabled?

It wasn't an email, it was a notification on my actual account. And I could see the location and the device name of the new person who logged in. I reset the password on my account, not through an email. And I didn't have 2 factor authentication before but I have set it up now. And now on the settings it says only I am logged into my account so I think it's all good?

I agree - it sounds like you're good now (particularly as you now have two-factor authentication enabled).

Was your previous password used for any other accounts / services / apps? If so, it might be wise to change those too.

I assume you the location and device name of the person who logged into your account weren't familiar to you?
