Kinde offers flexible tools for customizing authentication pages to match your product's branding, with three main approaches: basic customization, advanced customization using code and CSS, and faceless customization with hosted pages. The basic option allows quick personalization through built-in tools to adjust logos, colors, fonts, and messaging without needing a developer. For teams with design skills, the advanced option provides full control over styling with custom CSS, enabling pixel-perfect designs and seamless integration with your brand's experience. The faceless method allows the creation of custom sign-in and sign-up pages with control over user flow while Kinde handles authentication in the background, making it ideal for those who want a balance between customization and simplicity. Kinde's approach supports iterative design, enabling teams to start with basic features and advance as their needs evolve, with extensive documentation and support available for guidance.
