Entra Custom Branding

Branding your Microsoft Entra ID sign-in experience isn’t just about aesthetics—it’s a strategic move that strengthens user trust, security posture, and phishing resistance.

Here's why it's smart:

Security Benefits of Custom Branding

• Reduces Phishing Risk: Attackers often mimic Microsoft’s default login pages to trick users into entering credentials. A custom-branded sign-in page makes it easier for users to spot fakes—because they’re trained to expect your logo, colors, and layout.
• Boosts User Confidence: When users see familiar branding (like your logo or even a Shih Tzu watermark), they feel reassured that they’re logging into a legitimate system. That trust reduces hesitation and improves adoption.
• Supports Security Awareness Training: You can use branding as part of your internal security messaging. For example, include a footer like: “If this page doesn’t look like this, don’t sign in—report it.”

Upload Your Branding Assets

• Favicon: A tiny icon that appears in the browser tab—like your brand’s digital fingerprint. Helps users instantly recognize your site.
• Background Image: The large image behind the sign-in box. Sets the visual tone—can be sleek, scenic, or even include a subtle mascot watermark.
• Logos (Header, Banner, Square):
  • Header Logo: Appears at the top of the sign-in box. Best for horizontal logos.
  • Banner Logo: Used in some layouts—similar to header but with more space.
  • Square Logo: Shows up in places like consent prompts and mobile views. Good for icons or mascots.
• Set Background Color: A fallback color if the image doesn’t load. Also used in minimal layouts. Choose something that complements your logo.
• Choose Layout (Full-screen or Partial):
  • Full-screen: Background image fills the entire screen—great for immersive branding.
  • Partial: Sign-in box sits beside a smaller image—more compact and cleaner.
• Optional: Add Header/Footer Text: Custom messages like “Welcome to Malcolm Soto’s workspace” or security reminders like “If this page looks different, don’t sign in.”
