Google is using login challenges to protect your account against suspicious logins to Google Apps in the fight against cybercrime
With measures such as 2-Step Verification and Login Challenges, Google is continually improving security features to protect individuals and companies from cyberattacks.
Account hijacking is the practice of obtaining a valid user-id and password pair in to enable a bad-guy to access your account.
To combat this Google introduced login challenges:
“If we detect that an unauthorised person is attempting to access a user's account, we will present them with a Login Challenge that asks the person to verify their identity. We might send an SMS with a verification code to the user's phone and ask them to enter this code before we grant access to their account”
We believe the login challenges are a great idea and should be appreciated as an effective method to combat the bad-guys.
