Can I give a user access to cloud storage who doesn t have a GCP account

Question

Can I give a user access to cloud storage who doesn't have an account? I want this user to access the resource for a short span of time, Should he mandatorily have an account for this?

Answer 1

Yes, you could certainly do this. 

You can use the signed URLs, to give time-limited resource access to anyone in possession of the URL, regardless of whether they have a Google account. 

Signed URLs gives the user read, write, or delete access to that resource for a limited time. Anyone who knows the URL can access the resource until the URL expires. You specify the expiration time when you create the signed URL.
