Additionally, there are some common reasons for login failures, such as:<\/p>\n<h3><span class=\"ez-toc-section\" id=\"1_Invalid_or_Deleted_Passkey\"><\/span>1. Invalid or Deleted Passkey<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Ensure that you are using right passkey. If it was removed, corrupted, or created on a device you no longer use, Outlook Live may fail to authenticate.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Browser_Compatibility_Problems\"><\/span>2. Browser Compatibility Problems<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Outdated browsers can block passkey prompts, especially on Safari or older Chromium versions.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"3_Cached_Credentials_or_Corrupted_Cookies\"><\/span>3. Cached Credentials or Corrupted Cookies<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>I&#8217;ve shared the first fix option below, which addresses the reason for the authentication failure. This is because old login data saved in your browser can cause problems with passkey authentication.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"4_Cross-Device_Authentication_Failure\"><\/span>4. Cross-Device Authentication Failure<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>When using your phone to approve sign-ins on your computer, the verification sometimes fails due to Bluetooth or network issues. Several users have encountered this problem, so I can say that it doesn&#8217;t always work reliably.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"5_Wrong_profile_or_System_Update\"><\/span>5. Wrong profile or System Update<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Check for system updates, device security settings, and incorrect PC profiles, as these can also cause invalid passkey issues.<\/p>\n<p>So, if you&#8217;re having trouble logging into Outlook.live, you&#8217;ll need to be patient. Follow the solutions below one by one to try and fix the problem.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Solution_Outlook_Live_Passkey_Login_Problems\"><\/span>Solution: Outlook Live Passkey Login Problems<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<h4><span class=\"ez-toc-section\" id=\"Fix_1_Clear_Browser_Cache_and_Cookies\"><\/span>Fix 1: Clear Browser Cache and Cookies<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>If you haven&#8217;t cleared your browser&#8217;s cache and cookies in a long time, this can also cause login problems. Deleting them is necessary to ensure a secure login.<\/p>\n<ul>\n<li>Go to your browser&#8217;s history and delete all cookies and cached files.<\/li>\n<\/ul>\n<p>Note: Do not delete saved passwords if you have them stored in your browser.<\/p>\n<ul>\n<li>Restart your browser and try signing in again.<\/li>\n<\/ul>\n<p>Another option is to use incognito\/private mode.
