$ conan user [-h] [-c] [-p [PASSWORD]] [-r REMOTE] [-j JSON] [name]
Authenticates against a remote with user/pass, caching the auth token.
Useful to avoid the user and password being requested later. e.g. while you’re uploading a package. You can have one user for each remote. Changing the user, or introducing the password is only necessary to perform changes in remote packages.
positional arguments: name Username you want to use. If no name is provided it will show the current user optional arguments: -h, --help show this help message and exit -c, --clean Remove user and tokens for all remotes -p [PASSWORD], --password [PASSWORD] User password. Use double quotes if password with spacing, and escape quotes if existing. If empty, the password is requested interactively (not exposed) -r REMOTE, --remote REMOTE Use the specified remote server -j JSON, --json JSON json file path where the user list will be written to
List my user for each remote:
$ conan user Current user of remote 'conan-center' set to: 'danimtb' [Authenticated] Current user of remote 'bincrafters' set to: 'None' (anonymous) Current user of remote 'upload_repo' set to: 'danimtb' [Authenticated] Current user of remote 'conan-community' set to: 'danimtb' [Authenticated] Current user of remote 'the_remote' set to: 'None' (anonymous)
Change bar remote user to foo:
$ conan user foo -r bar Changed user of remote 'bar' from 'None' (anonymous) to 'foo'
Change bar remote user to foo, authenticating against the remote and storing the user and authentication token locally, so a later upload won’t require entering credentials:
$ conan user foo -r bar -p mypassword
Clean all local users and tokens:
$ conan user --clean
Change bar remote user to foo, asking user password to authenticate against the remote and storing the user and authentication token locally, so a later upload won’t require entering credentials:
$ conan user foo -r bar -p Please enter a password for "foo" account: Change 'bar' user from None (anonymous) to foo
The password is not stored in the client computer at any moment. Conan uses JWT, so it gets a token (expirable by the server) checking the password against the remote credentials. If the password is correct, an authentication token will be obtained, and that token is the information cached locally. For any subsequent interaction with the remotes, the Conan client will only use that JWT token.
Using environment variables¶
The CONAN_LOGIN_USERNAME and CONAN_PASSWORD environment variables allow defining the user and the password in the environment. If those environment variables are defined, the user input will no be necessary whenever the user or password are requested. Values for user and password will be automatically taken from the environment variables without any interactive input.
This applies also to the
conan user command, if you want to force the authentication in some
scripts, without requiring to put the password in plain text, the following can be done:
$ conan user --clean # remove previous auth tokens $ export CONAN_PASSWORD=mypassword $ conan user mysyusername -p -r=myremote Please enter a password for "mysusername" account: Got password '******' from environment Changed user of remote 'myremote' from 'None' (anonymous) to 'mysusername' $ conan upload zlib* -r=myremote --all --confirm
In this example, conan user mysyusername -p -r=myremote will interactively request a password
CONAN_PASSWORD is not defined.
The environment variable CONAN_NON_INTERACTIVE (or
general.non_interactive in conan.conf)
can be defined to guarantee that an error will be raise if user input is required, to avoid stalls in CI
Note that defining
CONAN_PASSWORD do not perform in any case an
authentication request against the server. Only when the server request credentials
(or a explicit conan user -p is done), they will be used as an alternative source rather than interactive user input. This means that for servers like Artifactory that allow enabling “Hide Existence of Unauthorized Resource” modes, it will be necessary to explicitly call conan user -p before downloading or uploading anything from the server, otherwise, Artifactory will return 404 errors instead of requesting authentication.
