To separate your business account login details from your personal account, you need to transfer the ownership of your business account to a different email address.
You can only do this on the web. Follow these steps:
Change the email address on your account from your business email to your personal email, if it isn’t already.
Go to your business account.
Click on your business name in the top-right corner.
Select Team members and payment approvals.
Choose to Add team member.
Invite your business email as a team member.
Accept the invite sent to your business email, and follow the steps to join the account as a new team member.
Log back into your business account with your personal email.
Go to Team, and select the team member with your personal email (the account owner) to go to your team member page
Choose Transfer ownership, then select the new team member with your business email to be the new owner.
Select Continue. The team member with your personal email will be removed from the business account. Your cards will be permanently deactivated.
You can now log into your business account using your business email address and the password you used when you accepted the invite. You should be able to log into your personal account with your personal email as usual.
Follow the same process if you have more than one business account on the same login. Just invite a different email address as a team member for your business account that you'd like to separate, and transfer the ownership to this team member.
