I have 2 personal adsence account with different names. One for me and one for my sister. I have 10+ websites i must divide my revenue for security, i have 2 accounts it is OK, but i am checking stats everyday in same PC. Is this a risky?
As long as they are legitimate accounts you should be fine. I manage more than one account and have never had any issues.
You may have different accounts for different entities. I have 2 accounts one my personal account which I use on my blogs and one for my company which I use on my websites. I check them on one computer and never had any problem.
