I already have Google-Authenticator on my iPhone - yay!
I want to have it on my iPad too (which I don't carry with me daily). I cannot see how to set that up in Google's online advice.
I don't want SMS as second factor because it is not in any way safe in 2017. SMS as a second factor is less secure than a strong password alone.
Go to https://myaccount.google.com/security/signinoptions/two-step-verification on your Mac/PC.
Generate, and perhaps print off some "Backup Codes"
Log out and log in to test one of those ten backup codes (perhaps a different browser so that login requires the second factor).
On your iPhone, delete the line in Google-Authenticator for the existing Google-Accounts setup.
Click on the pencil icon, to the right of the "Authenticator app (Default)" you already have.
Click "Change Phone", and show the new QR code the screen. In both iPhone and iPad scan the QR code. Yes, the same QR code twice. Note now that the one-time-passcode is the same on both. Do both quickly as there is only a certain amount of time to complete this in.
Note: I could not find a way of deleting the backup codes. I mean I can shred the printout, but can't see how to get the list of second-factors in Google-Accounts to drop the backup codes.

I'm trying to figure out what the best way to print from App Maker. I have a guess management app and I need a way to print out guest passes from app maker. I have some ideas, but I'm not sure what would work or be the acceptable best practice. These will print out on a 4x6 thermal printer. Any working examples would be greatly appreciated. I've only managed to get option two below to work without css formatting.
1) Open the guest info in a page fragment and print it. This would need to print the page fragment as displayed, unsure if this is possible in app maker.
2) Create an html page by passing the guests information, open the page in a new tab and use windows print.
3) Use a mailmerge of sort on a document on google drive and print with cloud print. I'm worried that the lag time might make this slow. I'm also unsure if it's doable.
Thank You
It sounds like you want to manually print them.
You could have a 'Visitor Card' template saved as either a Google Document or Google Sheet. When the visitor signs in, duplicate that document, write your visitors information to the appropriate cells/positions, then save as a PDF in a Google Drive location.
All of the above can automated, so you'll simply have to have a tab open at the Drive location and then print the file once saved. The saving process shouldn't take any longer than 5-10 seconds, which I think is a reasonable timeframe.
Another option, which is more technical, is you directly send a request to your printer to print. Although, this would depend on your printer and technical capabilities.
I'm running an A/B Test targeting 100% of iOS users with specific versions using a regex to match versions 2.1.27 and up, here's the regex in case it's relevant:
2\.1\.([3-9].|2[7-9])
I did not set any activation event for the experiment; meaning I left that field blank.
Now my question is: Who becomes part of the experiment? Anyone who opens the app with a matching version? Anyone who starts a session with a matching version? Anyone who engages with a matching session?
So far, it says the total number of users that have been exposed to the experiment is 9,6K. I'm trying to set up a funnel that only includes these users but I can't figure out one that shows me anything close to that number in the date range of the experiment.
Firebase Support says:
Firebase will determine if a user will be part of the experiment when your app do the activatedFetch method.
That's the answer I was looking for.
Here's the situation. I am trying to implement a system in a restaurant where each table has its unique QR Code. The QR Code is fixed and hard printed on the table. My application is basically a web page and the QR Code is simply a web page address with an encrypted parameter which identifies the table.
This system is already protected (to a certain degree) from pranksters by only allowing orders to come from the IP address of the Wifi connection. So you need to be at least connected to the restaurant's wifi to use this page. Doesn't protect from people outside the building, but that is another issue.
The problem occurs if a user comes today and scans the code for table 3 and places an order. If the user comes later and sits at table 5, I don't know how to stop them from loading the previously scanned link (for table 3) and place an order for table 3.
Having constantly changing time stamped QR Codes would address the problem, but that is impossible since the QR codes are fixed.
Is there a way for the page to "know" that it has been loaded from a QR Code Scan, or whether it was loaded from the browsing history? We are talking about pages loaded on a smartphone, so I guess that complicates matters.
Any help or pointers would be greatly appreciated! :)
In short, no. There's usually no "refer" header which will tell you that a page has been loaded from a bookmark or retrieved from a scanner's history rather than scanned directly.
Having an ever changing QR code is not impossible (using eInk or a small display) but that doesn't solve the problem.
Here's how I would fix it.
User scans a code - example.com/table3 - the first thing they see is a map with table 3 highlighted on it.
Text says "If you're not at table 3, please scan the code on your table. If you are - click here to order." Or something like that.
Explain to the user that if they're not sitting at the correct table - someone else will get their food!
I have a classifieds webapp for our student union and want to create printable versions of the different ads, that students can print and distribute on the campus. To get further information, people should be able to read a QR code from the printout with their smartphone.
The question is: Can I encode both the phone number to call for the ad and the URL of the website in the QR code at the same time, so that people can scan the code and then select if they want to call the person or open the website of the ad?
I was thinking about using a vcard, but that would add that otherwise useless information to the peoples contacts list. Is there something like CSV data that Android correctly reads to achieve this? (And preferably iPhones, too)
Of course you can.
VCard is fine, it would enable other QR readers to parse it correctly - so your QR would be up to standard.
You wouldn't have to implement full RFC though, just the basic TEL, and URL fields.
My boss wants me to fashion a QR code so that when the user scans it, it displays a button that when clicked:
(1) Will take the user to our website.
(2) Will quietly send us a text message.
The purpose of #2 is to allow us to gather their phone number.
In addition to being a privacy violation, I'm pretty sure this (and any other means of achieving this), is technically impossible. Is that correct?
My understanding of QR codes is that they only contain text. That text may contain keywords which a good reader may parse and display buttons for. It seems the closest I can get to my employer's requirement is to use an SMSTO: link in the QR code, so that (given an appropriate reader) the user is prompted to send us an SMS, at which point we can get their number.
Can anyone think of another way of doing this?
(any other clarification also welcome)
It is technically impossible.
As you say, the best you can do is create an smsto: link.
What you can do is create a code with the instruction
"Scan the code to receive our website by SMS"
Then, create a code with
smsto:123456:website
This will send the keyword "website" to a phone number. You'll need to set up a phone number which can auto-respond with the URL you want. There are commercial services which do this (depending on where you are in the world). Or look at a service like FrontlineSMS which can send the texts on your behalf.
