What characters should I use or not use in usernames on etcd?
ETCD version: 3.3.13

A is username，B is password,character : is special

A is username，B is password,character : is special

Is there any other way to add a user name with character : ?

[tangcong]

etcdctl can not add a user name with character ; , you can try to add special user name by clientv3. example.

[tangcong]

etcdctl user add hello:123 --no-password
etcdctl user passwd hello:123

it also works.

[tangcong]

it is better if username supports special characters :, can we add a password flag to optimize this issue? how do you think so? @mitake

[hehechen]

etcdctl user add hello:123 --no-password
etcdctl user passwd hello:123

it also works.

It doesn't work in etcd 3.3.13, showes flag provided but not defined: -no-password
what etcd version support --no-password ?

[tangcong]

etcdctl user add hello:123 --no-password
etcdctl user passwd hello:123

it also works.

this pr solved this issue. etcd version 3.4+.

@hehechen yeah the problem comes from the old flag (it comes from v2)like etcdctl user add <username:password>. A:B will be interpreted as user A whose password is B. As @tangcong shared --password flag can avoid this problem. I feel the behavior is confusing so I personally want to remove <username:password> notation...
