# What are custom sign-in credentials, and when do I need them?

They're a Client ID and Client Secret you create in Google's own console, so Google sees **you** as the app's owner. You only need them if Google blocks the normal sign-in — usually with a *"This app is blocked"* page — which happens most with work and school accounts.

Leave both fields blank to use the built-in defaults, which work for most personal Google Drive accounts. If you do create your own, they only work for the accounts you sign in with, so you stay in control of your own data. The fields are under **Advanced — custom sign-in credentials** in the Add Account sheet.
