Q:

Why Are Mining Passwords 'x'

In any of the 'get started mining' type sites, I see that password is always x. In xmr-stak, it seems to suggest putting in 'mostly empty or x' as a password. Does this really mean I should be using some default one-character password, or am I just misreading?

A:

The 'x' is just a placeholder. It is up to the pool to decide how to use it. It is just an optional message that could be passed between a miner and a pool. For example, often pools allow miners to use it to assign individual workers names/IDs.
