Clear and concise description of the problem

I have multiple Personal Projects which share the same Secrets. I have to configure the Secrets for each Project. It would be better to have Secrets on a User Level.

Suggested solution

We already have Secrets on Global and Organisation Level Level. Why not on a User Level?
