autoawsmfa --profile <profile name> mfa --add-secrete

Profile name should exist in '~/.aws/credentials' for posix or in '%UserProfile%.aws\credentials' fot NT/windows

Get Secret

autoawsmfa --profile <profile name> mfa --get-token

If the secret is not added earlier for the specified profile, it will prompt to add secret

Delete Secret

Delete secret from keyring

autoawsmfa --profile <profile name> mfa --del-secret

Optional arguments that can be used

Non AWS MFA

This can be used to register the non AWS secrets such as OKTA or any thirdparty MFA enabled application. This option prompts for application name and user name to register and retrieve token. You shoud make a note of application name and user name while registring as currently there is no option to list view the secrets stored.

autoawsmfa mfa --non-aws --get-token
