## Common questions

### What security check should I enable for TeamCity login after creating the first user?

Enable two-factor authentication after creating your first user. It adds a temporary code or app check at login and stops someone with only your password from changing builds, projects, or settings.

### What limits apply to TeamCity self-hosted without a commercial license?

A community post says that, without a commercial license, TeamCity is limited to 100 build configs and 3 build agents, or similar. The same thread says that seemed far more than enough to the asker.

### Where should I look before reporting a slow or misconfigured TeamCity server?

Check the TeamCity Common Problems page before reporting an issue. It points to pages for configuring server memory settings and reporting server slowness issues.

### Where are TeamCity general FAQ answers collected?

The TeamCity Support site has a TeamCity FAQ section. It contains frequently asked questions and answers about TeamCity.
