How to view QR code in Gmail?
To identify ourselves in this way we only need to access from accounts.google.com/sesame and read the QR code from our Android with a reader such as Google Goggles. We have to read the code within four minutes, otherwise it will expire and we will have to renew it for a new one.
Why is the QR code not displayed?
If you place the cell phone too close or too far away from the code, it will not be able to scan it. Place it about 30 cm away from the QR code and move it closer and closer. Some phone cameras focus worse than others at close distances, so you may need to move your phone a little further away.
How do I make the QR code appear?
On your compatible Android phone or tablet, open the built-in camera app. Point the camera at the QR code. Press the banner that appears on your Android phone or tablet. Follow the on-screen instructions to complete the login process.

My qr code
What is a QR code (Quick Response code) is a module for storing information in a dot matrix or a two-dimensional barcode. Unlike a conventional barcode (e.g. EAN-13, Code 3 of 9, UPC), the information is encoded within a square, allowing a large amount of alphanumeric information to be stored.
A QR reader is used to read these codes. Smartphones also allow these codes to be scanned through the camera and decoded using one of the specific applications for this purpose, such as QR Droid:
When the code is captured with the QR application installed on the phone, it is decoded and the information it contains is displayed on the screen: a link to a Web site, an image, a text, a patient file, information about a monument, etc.
A qr code can be forged
When scanning a QR code with the Nest app using a cell phone or tablet, it will not flash, so it is important that you do this in a place with good lighting. Turn on more lights or raise the blinds and try scanning the code again.
Sometimes the autofocus feature can become inaccurate with the pattern on a tablecloth, carpet or wall, and this prevents the code from scanning. If the Nest product you are installing is on a patterned background, try placing it on a smooth surface and re-scan the code.
Place the Nest product on a countertop, table or other firm surface. If it moves too much, the mobile camera may not focus the code correctly. Try resting your elbows on the table to keep the phone from moving.
Some phone cameras focus worse than others at close distances, so you may need to move your phone a little farther away. Try positioning the phone so that the QR code is inside the blue box on the Nest app and move it away a little at a time.
