I want to ask if the recently well used 2-step verification does actually keep the online accounts safe. (by using a mobile phone) ?

  1. Assuming access to phone stays on our concern.

    • What could be the case, that someone is able to get access over it ?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.

2-step verification (or 2-factor authentication) is a step above 1-factor authentication (just a password) because it requires the user to have access to something (generally, a specific cell phone) as well as know the password in order to log in to an account.

However, 2-factor verification does not eliminate any security concerns. Researchers have shown many times that 2-factor authentication can be compromised. See these articles for some examples:

Using 2-step verification is more secure than not using it, by a long shot, but it can still be compromised. Like any other security method, you can always make something more secure, but you'll probably never make it completely secure.
