What are tawk.to cookies and what do they do?

The tawk.to widget uses several types of cookies to help you communicate more effectively with your customers.

What are cookies?

Website cookies are small snippets of data shared with site visitors and stored in their computer drives when they land on web pages.


Cookies save you time by keeping you logged in to your favorite websites, recognizing you when you return, and displaying languages based on your location.


They enable you to adjust widget greetings for time zones. They even allow you to share special offers based on specific page visits.


Just like home-baked cookies, web cookies don’t last forever. The expiry time dictates how long they are stored or shared.


Let’s take a quick look at what they do and why they are important.

Visitor tracking cookies

The tawk_uuid_propertyId cookie tracks unique visitors to a website. It uses Universally Unique Identifiers (UUIDs) made up of randomly generated 128-bit numbers. This cookie is dynamic and changes based on property ID values. 


To view your property ID, select ⚙️Administration in the lower-left corner of the Dashboard. You’ll find it under Property ID in the Overview panel.

The first time you visit a website, the website’s server generates a unique code and sends it to be stored on your computer as a cookie.


The tawk_uuid_propertyId cookie does not store your personal details. However, it can help websites remember your preferences and create a more personalized user experience.

Session cookies (ss)

When you log into a website with your name and email. Your credentials are verified and a session ID is created, which is sent to your computer in a session cookie (ss). That way, you don’t have to log in every time you visit the page.


Session cookies don’t contain any personal data. The data is not shared, and no third parties could access or identify you even if they did view the information in the cookies.


After you log out or close the browser, the session cookie is automatically deleted.

Connection management cookies

When a visitor opens a page from a website and our widget is already appearing in multiple browser tabs on that site, the TawkConnectionTime cookie manages requests to load the widget simultaneously


The twk_idm_key cookie is a session cookie that is added only if no twk_uuid is found. It is destroyed once the page is closed. Its purpose is concurrency control. If multiple pages are open at the same time, then multiple connection requests will be made at the same time. A unique identifier is generated to lock a page from making the connection first. Once a connection is made, it will release the lock and the rest of the pages will then be able to make the connection.

Preference cookies

Preference cookies tailor the visitor experience on your website by remembering details such as preferred language or video player settings.


While it’s possible to block all cookies in your browser, some features in tawk.to will only function correctly with cookies. Our goal is to continually improve your experience on our site.

How does Visitor Consent affect Cookies?

If a website has enabled a consent form for the chat widget, then no cookie will be added until the visitor submits the consent form. If no consent form is enabled, the cookie will be stored without consent.
