\n\t\n\t\t\t\tWhat is \u201cTwo-Factor Authentication\u201d?<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

Two-factor authentication (2FA) is an additional layer of security that Seznam.cz offers to its users. Once enabled, every login attempt must be approved via one of your verification devices.<\/p>\n\n\n\n

You\u2019ll be notified, for example, if someone guesses your password and tries to access your account. You can then choose to allow or deny the login attempt.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\tDo I have to enable two-factor authentication? I\u2019m not interested.<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

No, you don\u2019t. Enabling two-factor authentication is completely optional. It\u2019s entirely up to you whether you want to use this security feature or continue signing in as you have until now.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\tI don\u2019t want to give you my phone number!<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

You won\u2019t be able to set up two-factor authentication without verifying a valid phone number.<\/p>\n\n\n\n

Your verified phone number acts as a backup if you want to log in using 2FA but don\u2019t have access to any of your verification devices.<\/p>\n\n\n\n

The verified number can also help you recover a forgotten password more easily.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\tHow do I set up two-factor authentication?<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

You can find a step-by-step guide in our Help section under \u201cEnabling Two-Factor Authentication.\u201d<\/p>\n\n\n\n

Note that to enable and use 2FA, you\u2019ll need to install and use an authenticator app. You can choose from a wide range of apps\u2014popular options include Authy, Google Authenticator, and Microsoft Authenticator.<\/p>\n\n\n\n

If you use email programs or apps (like Outlook, Thunderbird, etc.), you\u2019ll also need to set up a new password for mail protocols such as IMAP\/POP3 and SMTP.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\tWhat\u2019s the difference between a verification device and a trusted browser?<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

A verification device<\/strong> is a Seznam.cz browser or app where login notifications will appear, allowing you to approve or deny sign-in attempts.<\/p>\n\n\n\n

A trusted browser<\/strong> is one where, after logging in and verifying the attempt, you\u2019ve selected an option to skip verification for future logins in that browser.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\tHow can I set Internet Explorer or Microsoft Edge as a trusted browser?<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

Unfortunately, you can\u2019t. Internet Explorer and Microsoft Edge do not support the required technologies. With these browsers, login confirmation will always be needed via a verification device. The only exception is the Microsoft Edge app on Android, which can be set as a trusted browser.<\/p>\n\n\n\n

You\u2019ll see the same limitation with browsers on outdated systems like Windows Phone and Windows 10 Mobile\u2014on those platforms, no browser can be set as trusted.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\tI don\u2019t have a verification device with me\u2014what now?<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

If you’re trying to log in but don\u2019t have access to any of your registered verification devices, you can choose to receive an SMS code sent to your verified phone number to complete the login process.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\tI don\u2019t have my verification device or verified phone\u2014what now?<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

If you’re trying to log in but don\u2019t have access to any verification device or your verified phone, unfortunately, you won\u2019t be able to log in. You\u2019ll need to wait until you regain access to at least one of them. There\u2019s no workaround.<\/p>\n\n\n\n

This is why we strongly recommend setting up more than one verification device.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\tI\u2019ve permanently lost access to my verification devices and verified phone<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

We\u2019re very sorry, but in that case, you will no longer be able to access your account.<\/p>\n\n\n\n

Again, this is why we recommend setting up more than one verification device.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\tWhat happens if I reinstall or delete the verification device?<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

Each installation of the Seznam browser for desktop or the Seznam.cz mobile app has a unique identifier tied to it. Reinstalling or installing the app anew changes this identifier, and the original verification device will no longer be valid.<\/p>\n\n\n\n

So be careful!<\/p>\n\n\n\n

This is another reason why we recommend setting up more than one verification device.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\tIs one verification device enough?<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

Yes, one verification device is technically enough for two-factor authentication. But if you lose access to that device, your only way to log in will be to receive an SMS code at your verified phone number.<\/p>\n\n\n\n

As explained in previous questions, there are several ways to accidentally lock yourself out of your account. That\u2019s why we always recommend setting up more than one verification device.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\tHow do I completely disable two-factor authentication on my account?<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

To disable two-factor authentication, simply remove all your verification devices one by one. Once all devices are removed, you\u2019ll be able to log in again using just your password, without the need for further verification.<\/p>\n\n\n\n

However, you\u2019ll also no longer receive alerts if someone guesses your password and tries to log into your account.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\tI\u2019m not seeing login notifications in the Seznam browser<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

The Seznam.cz desktop browser includes a feature that checks for new emails and monitors login activity. If you\u2019ve turned this feature off, you\u2019ll need to enable it again.<\/p>\n\n\n\n

In the browser settings, look for the Quick Launch<\/strong> option.<\/p>\n\n\n\n

If you\u2019re not receiving login notifications in the Seznam.cz mobile app, check your device settings to ensure that notifications are enabled.<\/p>\n\n\n\n

You may also need to wait a little\u2014the notification might be delayed. If it doesn\u2019t arrive, you can choose Resend<\/strong> under the „Having trouble verifying?“ option during login.<\/p>\n\n\n\n

If notifications still don\u2019t appear, try switching networks\u2014for example, use mobile data instead of Wi-Fi.<\/p>\n\n\n\n

If notifications only appear when you manually open the Seznam.cz app or browser, your phone might be putting the app to sleep in the background. Each device handles this differently\u2014check your battery settings for power-saving or optimization features and make sure the Seznam.cz app is excluded. Refer to your device\u2019s user manual for details.<\/p>\n\n<\/div><\/details>\n\n\n\n

\n\t\n\t\t\t\t I can\u2019t connect through my email program<\/strong>\n\t\t\t<\/summary>\n\t
\n\n

This is expected behavior if you have enabled two-factor authentication. You\u2019ll need to generate a special password to access your account via email protocols such as IMAP\/POP3 and SMTP. This password is separate and used exclusively for email clients.<\/p>\n\n<\/div><\/details>\n\n<\/div><\/div>\n\n<\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":6,"featured_media":0,"parent":1967,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"page-sidemenu","meta":{"_acf_changed":false,"_relevanssi_hide_post":"","_relevanssi_hide_content":"","_relevanssi_pin_for_all":"","_relevanssi_pin_keywords":"","_relevanssi_unpin_keywords":"","_relevanssi_related_keywords":"","_relevanssi_related_include_ids":"","_relevanssi_related_exclude_ids":"","_relevanssi_related_no_append":"","_relevanssi_related_not_related":"","_relevanssi_related_posts":"","_relevanssi_noindex_reason":"","footnotes":""},"page_category":[81],"page_tag":[],"service_status_category":[],"class_list":["post-1971","page","type-page","status-publish","hentry"],"acf":[],"lang":"en","translations":{"en":1971,"cs":168},"pll_sync_post":[],"_links":{"self":[{"href":"https:\/\/o-seznam.cz\/napoveda\/ucet\/wp-json\/wp\/v2\/pages\/1971","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/o-seznam.cz\/napoveda\/ucet\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/o-seznam.cz\/napoveda\/ucet\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/o-seznam.cz\/napoveda\/ucet\/wp-json\/wp\/v2\/users\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/o-seznam.cz\/napoveda\/ucet\/wp-json\/wp\/v2\/comments?post=1971"}],"version-history":[{"count":2,"href":"https:\/\/o-seznam.cz\/napoveda\/ucet\/wp-json\/wp\/v2\/pages\/1971\/revisions"}],"predecessor-version":[{"id":1975,"href":"https:\/\/o-seznam.cz\/napoveda\/ucet\/wp-json\/wp\/v2\/pages\/1971\/revisions\/1975"}],"up":[{"embeddable":true,"href":"https:\/\/o-seznam.cz\/napoveda\/ucet\/wp-json\/wp\/v2\/pages\/1967"}],"wp:attachment":[{"href":"https:\/\/o-seznam.cz\/napoveda\/ucet\/wp-json\/wp\/v2\/media?parent=1971"}],"wp:term":[{"taxonomy":"page_category","embeddable":true,"href":"https:\/\/o-seznam.cz\/napoveda\/ucet\/wp-json\/wp\/v2\/page_category?post=1971"},{"taxonomy":"page_tag","embeddable":true,"href":"https:\/\/o-seznam.cz\/napoveda\/ucet\/wp-json\/wp\/v2\/page_tag?post=1971"},{"taxonomy":"service_status_category","embeddable":true,"href":"https:\/\/o-seznam.cz\/napoveda\/ucet\/wp-json\/wp\/v2\/service_status_category?post=1971"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
