If an email gives you a link to login to your account – don’t.
Its not safe, that link may take you to a site which is not genuine and when you type in your credentials they can capture them. Imagine if that’s your bank account details you’ve just given to somebody else.
No the safest way to do this is to go your own, usual way to your bank login. So close the email and then use your browser and go to your bank web site completely independently. That way you’ll be using the bank’s site not one that looks like it.
