If you're suspicious about a password query, do this first

Cybercriminals can use password query windows to try to steal sensitive data in so-called phishing attacks, computer security experts warn.

Password query windows that suddenly pop up on your smartphone or computer can be legitimate security measures – or they could be an attempt to steal your personal data. 

Cybercriminals use these windows to try to steal sensitive data in so-called phishing attacks, computer security experts have warned.

Apple's iOS, for example, asks users at irregular intervals to enter their username and password. Criminals can fake these queries to steal the user's data.

However, there's a simple trick you can use when confronted by a sudden password query that you're suspicious of.

IT security expert Per Thorsheim recommends deliberately entering the wrong password to see what happens. — dpa
