# User management **(CORE ONLY)**
GitLab provides Rake tasks for user management.
## Add user as a developer to all projects
To add a user as a developer to all projects, run:
```shell
# omnibus-gitlab
sudo gitlab-rake gitlab:import:user_to_projects[username@domain.tld]
# installation from source
bundle exec rake gitlab:import:user_to_projects[username@domain.tld] RAILS_ENV=production
```
## Add all users to all projects
To add all users to all projects, run:
```shell
# omnibus-gitlab
sudo gitlab-rake gitlab:import:all_users_to_all_projects
# installation from source
bundle exec rake gitlab:import:all_users_to_all_projects RAILS_ENV=production
```
NOTE: **Note:**
Admin users are added as maintainers.
## Add user as a developer to all groups
To add a user as a developer to all groups, run:
```shell
# omnibus-gitlab
sudo gitlab-rake gitlab:import:user_to_groups[username@domain.tld]
# installation from source
bundle exec rake gitlab:import:user_to_groups[username@domain.tld] RAILS_ENV=production
```
## Add all users to all groups
To add all users to all groups, run:
```shell
# omnibus-gitlab
sudo gitlab-rake gitlab:import:all_users_to_all_groups
# installation from source
bundle exec rake gitlab:import:all_users_to_all_groups RAILS_ENV=production
```
NOTE: **Note:**
Admin users are added as owners so they can add additional users to the group.
## Control the number of active users
Enable this setting to keep new users blocked until they have been cleared by the administrator.
Defaults to `false`:
```plaintext
block_auto_created_users: false
```
## Disable two-factor authentication for all users
This task disables two-factor authentication (2FA) for all users that have it enabled. This can be
useful if GitLab's `config/secrets.yml` file has been lost and users are unable
to log in, for example.
To disable two-factor authentication for all users, run:
```shell
# omnibus-gitlab
sudo gitlab-rake gitlab:two_factor:disable_for_all_users
# installation from source
bundle exec rake gitlab:two_factor:disable_for_all_users RAILS_ENV=production
```
## Rotate two-factor authentication encryption key
GitLab stores the secret data required for two-factor authentication (2FA) in an encrypted
database column. The encryption key for this data is known as `otp_key_base`, and is
stored in `config/secrets.yml`.
If that file is leaked, but the individual 2FA secrets have not, it's possible
to re-encrypt those secrets with a new encryption key. This allows you to change
the leaked key without forcing all users to change their 2FA details.
To rotate the two-factor authentication encryption key:
1. Look up the old key. This is in the `config/secrets.yml` file, but **make sure you're working
with the production section**. The line you're interested in will look like this:
```yaml
production:
otp_key_base: ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
```
1. Generate a new secret:
```shell
# omnibus-gitlab
sudo gitlab-rake secret
# installation from source
bundle exec rake secret RAILS_ENV=production
```
1. Stop the GitLab server, back up the existing secrets file, and update the database:
```shell
# omnibus-gitlab
sudo gitlab-ctl stop
sudo cp config/secrets.yml config/secrets.yml.bak
sudo gitlab-rake gitlab:two_factor:rotate_key:apply filename=backup.csv old_key=<old key> new_key=<new key>
# installation from source
sudo /etc/init.d/gitlab stop
cp config/secrets.yml config/secrets.yml.bak
bundle exec rake gitlab:two_factor:rotate_key:apply filename=backup.csv old_key=<old key> new_key=<new key> RAILS_ENV=production
```
The `<old key>` value can be read from `config/secrets.yml` (`<new key>` was
generated earlier). The **encrypted** values for the user 2FA secrets will be
written to the specified `filename`. You can use this to rollback in case of
error.
1. Change `config/secrets.yml` to set `otp_key_base` to `<new key>` and restart. Again, make sure
you're operating in the **production** section.
```shell
# omnibus-gitlab
sudo gitlab-ctl start
# installation from source
sudo /etc/init.d/gitlab start
```
If there are any problems (perhaps using the wrong value for `old_key`), you can
restore your backup of `config/secrets.yml` and rollback the changes:
```shell
# omnibus-gitlab
sudo gitlab-ctl stop
sudo gitlab-rake gitlab:two_factor:rotate_key:rollback filename=backup.csv
sudo cp config/secrets.yml.bak config/secrets.yml
sudo gitlab-ctl start
# installation from source
sudo /etc/init.d/gitlab start
bundle exec rake gitlab:two_factor:rotate_key:rollback filename=backup.csv RAILS_ENV=production
cp config/secrets.yml.bak config/secrets.yml
sudo /etc/init.d/gitlab start
```
