Thank you for posting 
SylviaE. Samsung Account now requires two-step verification for all accounts. 
You are able to change or add new numbers in the two-step verification menu. 
1. Go to Settings, then tap your profile image in the top right corner of the screen.
2.  Go to Password and security, then tap two-step verification.
3.  Verify the phone number you'll use to receive verification codes.
Hope this helps!
