Is academic certification safe?

Personally, I don't think the danger is great, because as long as your education has passed the declaration and certification, others can't use it to do anything.

Sms authentication

At present, you need to verify your academic information through SMS.

Fraud risk

The possible danger is that some movies use the information they know about you to deceive you, your family and friends.

Malicious promotion

Or some businesses will maliciously promote and sell things to you based on your information.
