Okta Sign‑In Widget: Missing Admin Control to Enforce Minimum Contrast Ratio

Administrators want a configurable option in the Okta Sign‑In Widget that enforces a minimum text‑to‑background contrast ratio (e.g., 4.5:1) for all custom HTML/CSS themes, ensuring WCAG AA compliance without relying on theme authors to self‑certify.

Enabling such a guardrail could invalidate existing themes that use brand‑specific colors below the threshold, requiring a migration window, testing, and possibly per‑application exemptions to avoid disrupting live login flows.

It remains unclear whether the contrast enforcement should be a global toggle, a per‑app setting, or a warning‑only mode that admins can override after review.

Should Okta provide a global admin switch to enforce the minimum contrast ratio? Should administrators be able to exempt specific applications from the enforcement? Should the platform include a preview that simulates how the chosen colors appear to users with various forms of color blindness before the setting is applied?
