Login branding

Dashboard → Branding. Three tabs: Logo & colors, Custom domain, Custom CSS (Pro+).

Logo & colors

Logo:

PNG or SVG.
Max size: 1 MB.
Recommended resolution: 320×80 px (landscape) or 80×80 px (square).
Upload by dragging or from your Files.

Colors:

Primary (buttons, links, focus states).
Login background (solid or image).

On the right you have a live preview showing how your login will look with those changes. It updates as you type the hex code. Refresh the tab if you like it.

Save: applies to the next session. Existing sessions keep seeing the old branding until logout.

Custom domain (Pro+)

If you want the login to live at auth.yourapp.com instead of auth.your-slug.prysmid.com:

“Custom domain” tab. Enter your domain.
We give you a CNAME value. Configure it in your DNS (Cloudflare / Route 53 / wherever).
Click “Verify”. We validate the CNAME.
When it propagates (1-15 min), we issue a TLS cert via Let’s Encrypt.
Status flips to active. Your app starts using the new issuer.

Custom CSS (Pro+)

If palette + logo isn’t enough, inject additional CSS. “Custom CSS” tab. Syntax-highlighted editor. Limits:

No JavaScript.
Max 64 KB.
No @import of remote fonts (you host them).

We validate syntax on save; if it breaks page CSS we tell you before applying. Automatic backups of prior versions; you can revert.

Toggle “Show Prysm:ID footer”. Pro+ only.

Preview in other languages

If your workspace has users in multiple languages, preview in Spanish, English, Portuguese, French via the selector top-right of the preview. Layout is the same; what changes is label copy.

Per-tenant branding (Pro+)

Same section, but you enter from Workspace → Tenants → <tenant> → Branding. Overrides apply only when the OIDC flow arrives with tenant_hint=<tenant>. Without a hint, the workspace branding wins. More details at /integrate/custom-branding →
