.SH "NAME"
depot_tools_gerrit_auth \- Gerrit authentication for depot_tools
.SH "DESCRIPTION"
.sp
The Chromium \fBdepot_tools\fR(7) suite contains many tools which may need to authenticate to Gerrit\&.
.sp
Gerrit uses OAuth for authentication\&. For depot_tools, OAuth is handled by \fBgit\-credential\-luci\fR\&.
.sp
Authentication is needed both for Gerrit API calls made by depot_tools and for operations done directly by Git (e\&.g\&., \fBgit push\fR, \fBgit fetch\fR)\&.
.sp
For Gerrit API calls, depot_tools uses \fBgit\-credential\-luci\fR out of the box, but for Git, you need to modify your Git configuration to use \fBgit\-credential\-luci\fR\&.
.SH "GIT CONFIGURATION"
.sp
You need to configure Git to authenticate to Gerrit\&. While depot_tools can help set up the necessary configuration (\fBgit cl creds\-check\fR), you can also do it manually\&.
.sp
You need to add the following lines to your Git config:
.sp
.if n \{\
.RS 4
.\}
.nf
[credential "https://chromium\&.googlesource\&.com"]
helper =
helper = luci
.fi
.if n \{\
.RE
.\}
.sp
.sp
This tells Git to use \fBgit\-credential\-luci\fR\&. The first empty value line is needed to reset the helper list to prevent conflicts\&.
.sp
You should copy this for each Gerrit host you use\&.
.sp
For Googlers, see go/chrome\-gerrit\-auth\&.
.SH "CREDENTIAL HELPER"
.sp
\fBgit\-credential\-luci\fR is a Git credential helper that can provide OAuth credentials for Gerrit\&.
.sp
You will need to set up your OAuth credentials first by running \fBgit\-credential\-luci login\fR\&. After that, it will be able to provide credentials to authenticate Git commands, if you have configured it according to the previous section\&.
.sp
\fBgit\-credential\-luci\fR only keeps one active login session at a time per OS user\&.
.SH "CHROMIUM DEPOT_TOOLS"
.sp
Part of the chromium \fBdepot_tools\fR(7) suite\&. These tools are meant to assist with the development of chromium and related projects\&. Download the tools by checking out the \m[blue]\fBgit repository\fR\m[]\&\s-2\u[1]\d\s+2\&.
