Does it matter if I use a different email on the CMU portal than I do on Naviance and CommonApp?

The CMU applicant portal is unlike a lot of others – instead of asking me to set a password, it logs me in through google – and as a result, I’m not able to share the pass/login with my mom so she can check on my status. I thought I could perhaps make a new email that I am comfortable sharing with her, and link that account alone to that email, but I’m not certain it’ll work with my CommonApp and Naviance being linked to my other account. So basically, would it affect me negatively if I did this?
