Now your friends can use your Chromecast without stealing your Wi-Fi

Your friends can now easily cast videos to your Chromecast thanks to a new feature called guest mode. The new mode allows anyone in the room with an Android device to jump on your Chromecast — even if they're not connected to your Wi-Fi network. Enabling guest mode on your Chromecast is just a few taps away.

How to enable guest mode in the Chromecast app:

  1. Tap Devices, select your Chromecast.
  2. Tap Guest mode.
  3. Slide guest mode to On.

That's all there is to it! Guest mode is available to anyone running Android 4.3 or higher (no support for iOS).

  • Does the Chromecast set up its own access point? Posted via the Android Central App
  • Basically, it's using some kind of ad-hoc WiFi mode, which is how you're able to find it and set it up initially.  I'm assuming this just an extension of that same functionality.
  • This is great news...
    Really happy the way things are going with the chrimecast LG G3 32gb
  • Agreed. I think it's the best physical product Google has ever launched. Nexus 4
  • H LG G3 32gb
  • Can you enable this on the Nexus Player as well? If so, how?
  • Kinda awkward. hey bro, lemme get your wifi password. uh..... here's guest mode for chromecast.
  • Most people never set their network passwords. They leave it the default long password that came on their Comcast /Fios etc router. And it's typically in another room. This is easier then getting up and getting it for them or sending them to get it. Like way easier.. Not awkward, easy Nexus 4
  • Agreed friends with networks with keys like aviFKSyakV()Une3BDVafih$!@A:LIJFIH_*#()*&H
    I hear something like that and unless I'm spending the week I'm like thanks bro I'll manage on my own.
  • Dude! Thanks for posting my password! Posted via the Android Central App
  • LOL
  • But I keep my WiFi password something like "s0rry!w!11n€v€rTe11", so that I can remember easily but not easy to crack also. Posted from Mi3W via the Android Central App
  • ROTFL, everyone looks at me like I'm crazy when I give my wireless password to people, which is quite like that. Which is why I'm glad my new router has a guest network, which I set with a nice simple password that they can enter easily. Plus they can't see my stuff as a bonus :)
  • What router is that?
  • Most offer it, My Asus AC68U has a guest SSID mode.
  • Same here. I setup a guest network if someone needs to connect. But since I hardly ever give out the password I have to go into the router settings to remember it.
  • faced a similar scenario last week. will try this out next time I am at my friends place
  • If you can't trust your friends enough to give them your Wi-Fi password, maybe you need new friends. Posted via the Android Central App
  • Except it's very tedious to write in the password that comes with your FiOS router... It's a million characters long. Posted via the Android Central App
  • Luke gets it Nexus 4
  • You could always set up an NFC tag to let them connect. iDevices won't be able to take advantage, but, meh, no problem to me. Get an Android.
  • That sounds like a whole lot more effort than just changing your access point's wifi password to something more manageable. Sent from my Nexus 5, behind six proxies
  • Its actually really easy, and easier than changing your router password. And just in a sense of security, you don't want to dumb down you wifi password.
  • Well, there's always setting up an NFC tab/sticker to take care of that; it's convenient. This guest mode has potential, though - especially if you have guests over you are less familiar with (friend of a friend sort of thing).
  • So change the FiOS router password lol :)
    It's dead easy, you can do it from the web.
  • I don't know how FiOS is, but with Comcast and these routers that do TV/Internet/Phone they *really* don't want you configuring *anything*.  Last time I tried to manually configure a friend's router that was acting up, it took 3 FREAKING HOURS on the phone with Comcast trying to convince them to give me the admin password to the thing.
  • Both FiOS and Optimum with their new smart routers have an interface on-line right next to your billing information to access basic router settings, I can change the SSID, passwords, port forwarding you name it from optimum's website.
    FiOS wasn't quite as advanced but you could view or change the wireless password. I think you mistake was calling honestly, I've never called for the admin password. If it's not written on the device I just google default password <insert ISP here> on <insert make of router> . it hasn't failed me yet.
  • I turned off the built-in WiFi and have a Netgear AC router. Even when I did use the FiOS router first thing I did was change the SSID and password. If you're my friend I trust you with my WiFi password. If I don't trust you with my WiFi password you're not even my friend to begin with.
  • 1. not every guess is a friend.
    2. some guest/friends dont know when they've installed on their phones/tablets/laptops.
    3. maybe I dont want them to know what on my network ?
    4. privacy ?
  • I agree. I bet all my friends have my wifi code and I have theirs.
  • same here
  • I don't know the WiFi password of any of my friends' networks.
  • You don't get it Nexus 4
  • I prefer not to have any misunderstandings as to what they have access to while connected to my network. I also don't want to have to worry about what other networks their equipment has been connecting to and what it may have picked up while connected to it.
  • Several months ago I heard that the Chromecast would play an ultrasonic tone through your TV. The guest device would be able to hear it and pair. Can anyone confirm this?
  • Yes, it's the same method. Posted via the Android Central App
  • Idk.. The TV speakers and your microphone would have to be capable of those frequencies. And they're not. So it's probably just the code displayed on TV Nexus 4
  • Actually it does work with the ultrasonic tone tested myself Posted via the Android Central App
  • Interesting.. I'll have to try it sometime. Reason I say about the frequency range is I tried using a db meter app for fire alarm testing and the microphone couldn't handle the high frequency, so my readings were incorrect. So I assume Ultra high definitely couldn't work since I was testing within hearing range. Nexus 4
  • It works, I tried it this morning at my house.
    Got the code twice with no issue whatsoever.
  • they announced this months ago was wondering when it would actually be a thing
  • Does this mean I can now use Chromecast in hotels with web based sign in? Posted via the Android Central App
  • I doubt it. Looks like the chromecast has to be setup normally but it will allow content links to be sent from nearby devices that aren't on the same network.
  • No. The Chromecast still has to be connected to the network. This just means that the guest wanting to use it doesn't have to be connected. While this could solve the problem of your device not being able to locate the Chromecast on the hotel's network, you still have the bigger hurdle of actually connecting it to the network in the first place. HOWEVER, this could be helpful for someone wanting to connect the Chromecast to a large network, such as one at a college, where devices are isolated from each other. There, the issue isn't getting it connected, as long as the school allows manual device registration by entering its MAC address into a Web site. The issue is that, once it's connected, your phone/tablet/computer can't see it on the network. This would get you around that problem.
  • I do wish they would fix this, the chromecast is basically just a browser.
    Seems like it would be an easy fix to let the user just bring up a browser on chromecast that could be controlled by your phone and sign on to the hotel wifi.
  • Still can't do anything in the Chromecast without being connected to WiFi. Strange. I am glad I can now cast from my phone, while using hot spot. Posted via the Android Central App
  • Is this true? You can now cast while providing internet via hotspot from the same phone? This has the only thing preventing me from buying one
  • Yeah.... I can just see it now. People war-driving through neighborhoods during the Christmas season and casting porn on any open device they find.
  • If your gonna leave your device open, you deserve all the kiddie port you get. /I will have a seat right over there Posted by my soon to be retired Note 3
  • From Googles site "Your Chromecast then generates a random 4-digit PIN that is required to cast to it using guest mode."
  • So is there an option to password protect guest mode? Or if you turn it on can just anyone in the world within range of your Chromecast cast to it?
  • "Your Chromecast then generates a random 4-digit PIN that is required to cast to it using guest mode."
  • Oh ok. Thanks for that info.
  • Couldn't your neighbors use it then? Posted via the Android Central App
  • Where was this at Thanksgiving, when I had to let all my roommates friends of friends onto my network so we could play Cardcast?!
  • Cannot find guest mode on my Chromecast app. Chromecast app seems to be updated as well. Only options are uninstall or open through Google Play Store. Even after reboot of my phone.
  • Hey, does this mean it finally works in hotels etc?? That would be very good news indeed.. I'll try it later.
  • I guess I'm just not paranoid about friends peeking into my network. If i didn't feel that I could trust them to not do such things then they likely wouldn't be friends. As to anyone who I wouldn't trust in the house, they wouldn't be there anyway. If they were in the house without invitation, I don't suppose it would be to use my Chromecast.
