Hi, I’ve been trying to access Zoom via the web client. It asks me for a username and then I get this error: “User name is required. (300)”. I’ve also tried to input the username into the URL, according to this thread: > [@Force username when entering meeting using browser Zoom app](https://devforum.zoom.us/t/force-username-when-entering-meeting-using-browser-zoom-app/1102): > > Hi!   We were wondering if there is a way to enter a Meeting using the browser version instead of Zoom app, for example in Chrome, and force the name of the participant.   The link to enter the meeting is something like this: and when we fill the name and actually enter to the meeting: [https://zoom.us/wc/{IDMEETING}/join?pwd=&dn={PARTICIPANT\_NAME}&track\_id=&jmf\_code=&meeting\_result=](https://zoom.us/wc/%7BIDMEETING%7D/join?pwd=&dn=%7BPARTICIPANT_NAME%7D&track_id=&jmf_code=&meeting_result=)   We tried using the “dn” parameter but it also asks the user for the user name before entering the meet… But haven’t managed to get into a meeting. I’m wondering what I’m doing wrong 🈶 Anybody had an error like that before? Thanks in advance and wish you all the best! ---

Hi @kadriko06, If you are using the Web Client you can do so using the below example. Make sure to base64 the username for the un parameter [https://zoom.us/wc/{meeting-id}/join?prefer=1&un={base64-username}](https://zoom.us/wc/%7Bmeeting-id%7D/join?prefer=1&un=%7Bbase64-username%7D) Thanks ---

Hi, Thanks for the reply but as I said above, it still asks for name when I try to connect. For example when I go there: [https://zoom.us/wc/9610451213/join?prefer=1&un=VGFybW8=](https://zoom.us/wc/9610451213/join?prefer=1&un=VGFybW8=) It should have my name set as ‘Marko’ I believe but still asks for my name. Am I doing something wrong? Also, if there’s a password, will I just use URL like this? [https://zoom.us/wc/9610451213?pwd=QmFpSGtOL0t4cmtEU3J1Y3JMOFdqZz09/join?prefer=1&un=VGFybW8=](https://zoom.us/wc/9610451213?pwd=QmFpSGtOL0t4cmtEU3J1Y3JMOFdqZz09/join?prefer=1&un=VGFybW8=) Thanks in advance, really appreciate the help. All the best! ---

Hey @kadriko06, Gotcha, we have recently changed how the Web Client urls work for added security. You will have to enter your name and the captcha. Thanks, Tommy ---
