Once you have already set your email and confirmed it on the left menu - Account - Email Address.
You will be able to add extra security to your account by adding the security acess by email. This will ask you for a confirmation everytime a new IP adress or device tries to access your account.
How to set security access by email?
Go to the Left Menu - Account - Security
The following window will open, click on SECURITY ACCESS BY EMAIL.
Now you have to tick the box saying "Ask verification by email"
You will now receive a verification email whenever you try to login, unless if you disable that option again, and your account security will be set to "High".
We strongly advise you to also add the Two-Factor protection.
