A change here takes effect for every user on the instance the next time they load the relevant page, so it's worth understanding what a setting does before changing it, not just where to find it. ## How to Access Navigate to **Settings** > **Preferences**. Navigate to Settings > Preferences Every item under Preferences requires **Admin** access. Non-admin users don't see the Preferences menu at all, so if a teammate reports they can't find these settings, that's expected unless they've been made an admin. ## What's in Preferences The table below lists every setting under Preferences, in the order it appears in the product, with a short description of what each one does and a link to the full guide. | Setting | What it controls | Guide | | :------------------------- | :------------------------------------------------------------------------------ | :----------------------------------------------------------------------------------------------- | | **Theme** | Custom logo, monogram, favicon, and brand color palette | [Theme and Branding](/v2.0.x/how-to-guides/admin-guide/preferences/theme-and-branding) | | **Email** | SMTP server used to send notification, invite, and alert emails | [Email](/v2.0.x/how-to-guides/admin-guide/preferences/email) | | **Login Configuration** | Failed login lockout and JWT session expiry | [Login Configuration](/v2.0.x/how-to-guides/admin-guide/preferences/login-configuration) | | **Health Check** | Live status of the database, search index, migrations, and related dependencies | [Health Check](/v2.0.x/how-to-guides/admin-guide/preferences/health-check) | | **Profiler Configuration** | Which profiler metrics run by default, per data type | [Profiler Configuration](/v2.0.x/how-to-guides/admin-guide/preferences/profiler-configuration) | | **Search** | Search relevance, ranking, and per-asset-type field weighting | [Search Configuration Settings](/v2.0.x/how-to-guides/admin-guide/search-configuration-settings) | | **Lineage** | Default upstream/downstream depth and lineage view mode | [Lineage](/v2.0.x/how-to-guides/admin-guide/preferences/lineage) | | **OpenMetadata URL** | The base URL used to build links inside outgoing emails | [Email](/v2.0.x/how-to-guides/admin-guide/preferences/email#openmetadata-url) | | **Data Asset Rules** | Platform-wide metadata validation rules assets must satisfy | [Data Asset Rules](/v2.0.x/how-to-guides/admin-guide/data-asset-rules) | | **Learning Resources** | In-product learning content shown to end users | [Learning Resources](/v2.0.x/how-to-guides/admin-guide/learning-resources) | Custom Logo and Theme aren't separate settings.
