InstaWifi
InstaWifi makes it easy for you to connect and share wifi networks with your friends and family instantly through the use of NFC and QR codes. Simply tap your phone on a sticker, or scan a QR code to connect to a wifi network.
======================================================================
InstaWifi is only needed to generate the QR code for your wifi network. Once you have the QR code, any Android smartphone with the Barcode Scanner app by zxing (https://play.google.com/store/apps/details?id=com.google.zxing.client.android) installed can scan to automatically connect.
For the NFC features, InstaWifi needs to be installed on the device to read the NFC sticker correctly.
Interested in playing around with NFC but don't know where or what type of NFC stickers to buy? Donate a couple bucks to the developer and I will send you special Android-themed NFC stickers as a token of appreciation.
For more details, see the help section in the menu of the app.
======================================================================
PLEASE READ THE FOLLOWING before installing:If you rooted your phone, InstaWifi will ask for root on startup so that it'll automatically grab your WiFi password and security type so that you don't have to manually type it in. Root access is not required.
DO NOT share the QR code to people you do not trust. The QR code has your wifi network password embedded in the image, and should only be used to share with family or friends.
PERMISSIONS EXPLAINED:Storage
- External SD card access is used to save QR images onto the SD card so that GMail and other applications can retrieve the image and attach it to their app.
Network Communication
- NFC permission is used to read/write from a NFC tag, as well as for Android Beam. Also to view WiFi networks to populate the list of WiFi networks you've connected to.
System Tools
- To enable and disable WiFi.

Used to be a great app. But now, it keeps asking me to enable Wi-Fi on my phone when the Wi-Fi is enabled. @Jessie, any thoughts on updating the app for latest versions of Android and fixing the enable WiFi issue?
Kinda useless because you have to have the App on your phone to use, so basically instead of just giving someone your name/password your have to ask them to download this app that they'll probably never use again, just to connect to your WiFi!!??
I can't think what this app would be useful for since you need to install it to connect to WiFi. The whole purpose was to make it easier for guests to connect.
Cannot fit android 10 on Samsung Note 10,shows need enable wifi ,but it is on already.hope to update and fix the problem!
It would be cool if you could add information such as the proxy server, port, phase 2 authentication etc
Garbage town. Looks like it hasn't been updated on forever.
If you program an NFC with this app... It only works on phones that have this app downloaded
I believe it is definitely a good phone.
i really don't know... how to use.that...app .. will u make a video for this... thank you ☺️
What's app
If you can save networks, password or QR codes, I could not find out how to do it, which means you need to re-enter the password every time. Much quicker to just tell your friend the password rather than fiddling around with your phone for five minutes. Have not tried the NFC function.
Unlike other NFC WiFi tag writers, this one goes to the instawifi page on the play store if it's not already installed, making the process as painless as possible. I'd like to see the WAP security type automatically discovered though.
Very simple easy to use app which makes sharing wifi passwords a breeze. Only issue I encountered was when I used google goggles to scan the QR code. First it gave me a few random words instead and when it did seem to work it didnt link between getting the code and sending it to my wifi settings. However using barcode scanner it works flawlessly. Thanks for all the work gone into this! Xda ftw
Forcing people to use your app to connect to a WiFi network? The fact that I can set this up on a device and write to a tag or make a QR code is cool. However the NFC tag or QR code doesn't have the WiFi credentials. It just redirects who ever wants my WiFi network connection to the play store to download this app before connecting. Not cool! Would be nice if someone else could connect without requiring the app. Till then one star!
As a bonus, shows existing passwords for root users, saves me crawling around in the file manager to find password records
This is making life a lot easier for everybody who needs wifi access at my place. However I notice that the QR and NFC codes are set for WiFi to NOT connect automatically. This confuses return customers.
It does not save the passwords which is the reason I installed the app so pretty useless for me now
Passwords won't save besides that nice app! Very easy to use ... And for you're troubles of a great app I really needed to donate so please enjoy your lunch on me, thank you Jesse.
This app is well worth the install. Sharing a WiFi network with friends has never been easier. Even embeds the password in the qr code one nfc transmission.
Always giving the message force close and doesn't work, using Galaxy Nexus with paranoid android on 4.4.4
Easy login for guest wifi users. Slight stumbling block where users need to already have downloaded instawifi from another data connection, but otherwise very simple to use. Just tap and you'll be connected.
Won't uninstall properly. Hijacks tablet now on start up EVERY TIME and on going to Google play. I've even factory reset the device - still comes back.
It doesn't save your password and it brings you to the Google play store, right to their own app page.
The app now loads the password of saved networks by the looks of it. Writes the tag fast and the tag functions perfectly. Not much else to say. No problems so far.
App doesn't work as intended on newer android versions (lollipop and marshmallow). Can't read the passwords even with root access. Was once a great app.
Even if the app could not automatically retrieve passwords of my saved networks, it should at least be able to save the passwords after I've entered them into the app the first time.
For root users, the app reads the wrong WEP or WPA2 password from memory. Instead of the actual key, the app comes up with a random string of hex digits (which do not work).
This is an amazing app wish it had support for 802.1, it would make life at work so much easier.
I used this app on my s3 worked fine, on my s5 currently its unable to read the password and shows random numbers and letters (hash).
The app is very convenient to use. The QR code (and maybe the tag) can be read using other tools revealing the Wifi password. A solution for that would be that there is option to enter a 4 digit code that decrypts the info printed in the QR code (/stored in the tag). That would make it impossible to use the tag / QR code completely without the approval of the WIFI owner.
