Can’t login to RMQ rabbitmqctl list_users - ensure that the user exists rabbitmqctl change_password username password - to the correct change_password Still can’t login? Ensure that there’s only one tag on the user using the “list_users” eg: if you have

rabbitmqctl list_users
Listing users
vishal	[administrator,monitoring]

Logins will not work and they will fail, there must be one and only one tag on a single user. The official documentation is somewhat un-helpful here.

Note that since “administrator” does everything “monitoring” does, and “monitoring” does everything “management” does, you frequently only need to give each user a maximum of one tag.
