This alarming event once again highlighted the vulnerability of traditional passwords and the urgent need for stronger digital security. The solution?&nbsp;One example: unstealable passkeys<\/strong>.<\/p>\n\n\n\n<p>Passkeys represent a modern and highly secure authentication method that eliminates many of the risks associated with traditional passwords. These keys are stored exclusively on your device, integrated within password managers and operating systems, significantly reducing the risk of data breaches.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Traditional Passwords vs. Passkeys<\/strong><\/h2>\n\n\n\n<p>At first glance, passkeys may seem similar to autofill password features found on websites and mobile apps. However, their security model is fundamentally stronger. Unlike passwords, passkeys are stored exclusively in password managers, and their validity is verified through advanced cryptography\u2014without the need to transmit the actual key. This eliminates the risk of theft during transmission and makes phishing attacks ineffective.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Traditional Login<\/strong><\/h3>\n\n\n\n<p>When logging in with a password, the user enters it on their computer, which then sends it to the website\u2019s server for verification. The server checks the password and returns a response\u2014either successful or failed\u2014which is displayed to the user.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/blog.bart.sk\/wp-content\/uploads\/2025\/03\/unnamed-6.png\" alt=\"\" class=\"wp-image-13132\"\/><\/figure>\n\n\n\n<p>This process has multiple weak points where passwords can be compromised:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>The user stores the password insecurely<\/strong>\u2014such as writing it down on paper or saving it in an unencrypted document.<\/li>\n\n\n\n<li><strong>Someone observes them entering it<\/strong>\u2014for instance, when typing on a public device.<\/li>\n\n\n\n<li><strong>They enter it on a fake website<\/strong>\u2014phishing attacks can mimic login pages to steal passwords.<\/li>\n\n\n\n<li><strong>The password is intercepted during transmission<\/strong>\u2014especially if it&#8217;s sent without encryption.<\/li>\n\n\n\n<li><strong>Hackers access it directly from the service<\/strong>\u2014if a password database is breached.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Biometric Login:<\/strong><\/h3>\n\n\n\n<p>Unlike passwords, passkeys use a more complex yet far more secure authentication process:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/blog.bart.sk\/wp-content\/uploads\/2025\/03\/unnamed-7.png\" alt=\"\" class=\"wp-image-13134\"\/><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>How It Works<\/strong><\/h4>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>The user initiates login.<\/strong> Their computer sends a request to the server: <em>\u201cI want to log in.\u201d<\/em><\/li>\n\n\n\n<li><strong>The server responds with a challenge.<\/strong> This is a one-time code confirming that the login is happening in real-time.<\/li>\n\n\n\n<li><strong>The computer forwards the challenge to the password manager.<\/strong> The password manager securely stores passkeys.<\/li>\n\n\n\n<li><strong>The password manager prompts the user for authentication.<\/strong> This could be a system prompt, an approval request on another device, or biometric verification.<\/li>\n\n\n\n<li><strong>The user verifies their identity.<\/strong> This could be via fingerprint scanning, facial recognition, or a PIN.<\/li>\n\n\n\n<li><strong>The password manager generates a digital signature.<\/strong> This signature confirms the authentication request without exposing the passkey itself.<\/li>\n\n\n\n<li><strong>The signature is sent back to the computer.<\/strong><\/li>\n\n\n\n<li><strong>The computer transmits the signature to the server for verification.<\/strong><\/li>\n\n\n\n<li><strong>The server verifies the signature and grants access.<\/strong> The user is now securely logged in.<\/li>\n<\/ol>\n\n\n\n<p>Implementing passkeys requires additional effort from developers, including cryptographic library support, biometric authentication integration, and compatibility testing with password managers.

Passkeys are stored only on your device and verified through secure cryptographic signatures, greatly reducing the risk of misuse.<\/p>\n  <\/details>\n\n  <details>\n    <summary>Do I need special hardware to use passkeys?<\/summary>\n    <p>No. All you need is a modern device with biometric support (like fingerprint or face recognition) and a password manager that supports passkeys \u2013 such as Apple Keychain, Windows Hello, a Google account, or 1Password.<\/p>\n  <\/details>\n\n  <details>\n    <summary>Are passkeys suitable for businesses?<\/summary>\n    <p>Yes. Passkeys offer stronger security and better user experience, making them ideal for web platforms, internal systems, or customer portals. They also reduce password-related IT costs and improve trust.<\/p>\n  <\/details>\n\n  <details>\n    <summary>Can I use passkeys across multiple devices?<\/summary>\n    <p>Yes, if you use a password manager or cloud service that syncs your keys between devices. Apple, Google, and Microsoft already support this functionality.<\/p>\n  <\/details>\n\n  <details>\n    <summary>What happens if I lose the device with the passkey?<\/summary>\n    <p>Passkeys can be synced across multiple devices or backed up in the cloud. If you lose one device, you can use another or restore access using your account backup \u2013 just like with passwords.<\/p>\n  <\/details>\n\n  <details>\n    <summary>Are my biometric details (like fingerprint) ever shared?<\/summary>\n    <p>No. Your biometric data never leaves your device. It is used only locally to verify your identity. The passkey itself is never transmitted \u2013 only a secure signature is sent to confirm login.<\/p>\n  <\/details>\n<\/section>\n","protected":false},"excerpt":{"rendered":"In 2024, hackers orchestrated one of the largest cybersecurity breaches in history\u2014leaking nearly 10 billion passwords in a&hellip;","protected":false},"author":49,"featured_media":7547,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","csco_display_header_overlay":false,"csco_singular_sidebar":"","csco_page_header_type":""},"categories":[199,251],"tags":[771,767,758,748,770,757,750,773,754,760,772,769,449,774,766,764,751,763,746,753,756,762,759,755,765,752,761,749,768,747],"_links":{"self":[{"href":"https:\/\/blog.bart.sk\/en\/wp-json\/wp\/v2\/posts\/7548"}],"collection":[{"href":"https:\/\/blog.bart.sk\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/blog.bart.sk\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/blog.bart.sk\/en\/wp-json\/wp\/v2\/users\/49"}],"replies":[{"embeddable":true,"href":"https:\/\/blog.bart.sk\/en\/wp-json\/wp\/v2\/comments?post=7548"}],"version-history":[{"count":2,"href":"https:\/\/blog.bart.sk\/en\/wp-json\/wp\/v2\/posts\/7548\/revisions"}],"predecessor-version":[{"id":7636,"href":"https:\/\/blog.bart.sk\/en\/wp-json\/wp\/v2\/posts\/7548\/revisions\/7636"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/blog.bart.sk\/en\/wp-json\/wp\/v2\/media\/7547"}],"wp:attachment":[{"href":"https:\/\/blog.bart.sk\/en\/wp-json\/wp\/v2\/media?parent=7548"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/blog.bart.sk\/en\/wp-json\/wp\/v2\/categories?post=7548"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/blog.bart.sk\/en\/wp-json\/wp\/v2\/tags?post=7548"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
