Hi @jointnomwp9vh, welcome to Thunkable!
Be sure to check out our posts about How to ask Great Questions v2.0 and our Community Guidelines as you get started.
It is impossible for us to help you unless you can offer more detail or a screenshot of the blocks you are using to create the Firebase login.
As Tatian mentioned, if you are needing to pay someone for your services, please consider posting this in our Freelance / Paid Help Opportunities category.
Thank you!
