npm token create [--read-only] [--cidr=<cidr-ranges>]: Create a new authentication token. It can be --read-only or accept a list of CIDR https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing ranges to limit use of this token to. This will prompt you for your password, and, if you have two-factor authentication enabled, an otp.

npm token revoke <token|id>: This removes an authentication token, making it immediately unusable. This can accept both complete tokens (as you get back from npm token create and will find in your .npmrc) and ids as seen in the npm token list output. This will NOT accept the truncated token found in npm token list output.
