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\.
