How to View SSL Certificate Details in Browsers

Note: Many browsers have recently moved these details away from the "Padlock" icon to specialized menus to declutter the interface.

1. Google Chrome

Desktop (Windows / macOS / Linux)

Chrome has moved certificate details inside the "Tune" or "Site Info" menu.

1. Navigate to the website.

2. Click the "Tune" icon (two slider switches) or the Lock icon located to the immediate left of the URL address bar.

3. Click Connection is secure.

4. Click Certificate is valid.

5. A pop-up window will appear displaying the certificate details (Issued To, Issued By, and Validity Period).

    

Mobile (Android)

1. Open Chrome and visit the website.

2. Tap the Lock icon or Tune icon to the left of the address bar.

3. Tap Connection is secure.

4. Tap Certificate information.

5. You can now view the validity dates and issuer.

Mobile (iOS - iPhone/iPad)

Limitation Note: Chrome on iOS does not currently support viewing detailed SSL certificate technical data (like the SHA fingerprints or full hierarchy) natively. To view these on an iPhone, use Safari (instructions below).

2. Apple Safari

macOS (Safari 18.4 and newer)

Significant Change: In recent versions of Safari, clicking the lock icon no longer shows the certificate immediately.

1. Navigate to the website.

2. Click Safari in the top menu bar (system menu).

3. Select Connection Security Details...
