--os-auth-methods does not appear to be a standard part of osc
infact i cant find it in any openstack repo with 

i think this is the implemtaions 
https://opendev.org/openstack/keystoneauth/src/branch/master/keystoneauth1/loading/_plugins/identity/v3.py#L303-L340

this presumable is where it generates teh optins 

  options.extend([
            loading.Opt(
                'auth_methods',
                required=True,
                help="Methods to authenticate with."),
        ])


if i do openstack help --os-auth-type v3multifactor it does show up with the following text

--os-auth-methods <auth-auth-methods>
                        With v3multifactor: Methods to authenticate with. (Env: OS_AUTH_METHODS)

that does not say much but

https://opendev.org/openstack/keystoneauth/src/branch/master/keystoneauth1/tests/unit/identity/test_identity_v3.py#L762-L800
implies its a list

with that said there are no test for multifactor as far as i can see like this one 
https://opendev.org/openstack/python-openstackclient/src/branch/master/openstackclient/tests/functional/common/test_args.py#L66-L79

there also does not seam too be a release note declaring support.

so while keystone auth support multi factor im not sure that osc actully does

i specpec that the fild type is not correct and it is indeed been parsed as a string instead of a list of stirng field.
it might be fixable via keystoneauth but  it proably need osc support and testing.
