Auth0 linking two separate email accounts in authentication - edited

Several sites I use are using the Auth0 service. I noticed that on all of these sites, when I log in using my personal GMail address, the username it pulls is from a separate, business Google Workspace account. These two things shouldn’t be linked anywhere, my personal GMail is a separate email address and separate account from the business account.

Could someone help me figure out why this is happening, so I can fix it? Feels a little like a violation of privacy.

Hi @gnlambert and welcome to the Auth0 Community!

While it would look like Auth0 is linking your accounts, I can assure you that it is not, and your privacy is kept. What is happening behind the scenes is that your browser stores a session of the accounts you use. When you click on a “Sign in with Google” button, Auth0 redirects you to Google (the identity provider), and Google checks your browser for a session to know what accounts to display for you to choose from.

I can’t give much insight into how to set up your Google accounts so that this doesn’t happen, but perhaps using different browsers for personal and business accounts could work.

Have a great day!
Teodor.

Hi Teodor,

Thanks for getting back to me so quickly. Just to clarify, I’m not clicking a Sign in with Google button.

If I was using Sign in with Google, then it would make sense that I would see a list of all of the different email addresses that I’m currently signed into on that browser.

However, that’s not what happens. I go to the login page, which asks for just my email address. I type in my personal email address, and then I see the screen below. It shows my business name in Welcome and icon, but my personal email address in the login info. I sign in using a password, which is my preferred method of signing in to websites/apps. I’m still not sure why Auth0 would retrieve an account name from a separate email address, other than the one I’m using to log in.

I took a screenshot, but can’t embed it in this post.

Thank you,
Gabrielle
