Being discussed in #2567.

Sorry to come back to this but I have one remaining concern. At some point we thought it was not such a good idea to have a single underscore determine such different semantics. I think we should try to have different names... the name _setupRole was pretty good in that regard I think. We can have _setupOwner, but I don't know how we would handle revoke, unless we do _setupRole(..., false).

I personally think that a prefix underscore is clearly a mark of "this is internal, with no access check".

We already use this pattern in a lot of contracts, particularly transfer vs _transfer and approve vs _approve.
I think the logic is clear, and the discoverability is way better that way than if we use a different name.

How can I retrieve my account since it has been severely compromised and I cannot access my account to transfer to my fiat wallet or financial institution

Hello @Mehduzza420

This is not the place for this question. You should try your wallet's community channel.
