Secure mongodb replica-set

Hey all,

how do you secure your mongodb-replica-set?
atm i’ve generated a key and saved it on every replica-set - so far so good.

but now i want to have a user with access right on the rocketchat database - but how exactly should i generate it?

thx!

Should be able to create a user with the read role. Definitely google it. Tons of articles out there
