How to produce a "securely random" string token in Haskell?

I want to produce string tokens to implement the password reset functionality of a web app. They can be v4 UUIDs but it is not required.

I want each token to be "securely random" in the sense of this SO question. The system's entropy pool should be sampled for each generated token.

I found the uuid package, that generates v4 UUIDs. The docs mention that

we use the System.Random StdGen as our random source.

but it is unclear to me if this is enough.

Is there other library that I should use instead?
