Ok It is OK. The one is used in IPhone showed the profile name on the page where the code is entered, making it easy to remember the code for a particular profile.
Best for portwise.
Text doesn't scale - very hard to read on HD screens This works and I've used it for many years. Originally on a Nexus One, then Nexus S, the Nexus 4, Nexus 5 and now LG G2. The problem is that the codes generated seem to be a fixed size defined in terms of pixels. On older phones, with low DPI on the screens, the text was displayed in quite a readable way. Now, I am trying to read something which has got smaller and smaller and it's too small to read. Please fix. Another thing I'd like is the use of computer fonts for the codes - i.e. 0 and O (zero and the letter O) are clearly distinguished. A font that is designed to be wholly unambiguous would be best, and why not allow users to set the font size? Finally, it's actually quite a pain to have letters and numbers with mobile keyboards. Could you just stick to one or the other? With 26 upper case and 26 lower case letters, surely that is enough. Most banks just have a 6 digit number code, and I am sure that a 1 in a million chance of guessing is secure enough given this is a two factor solution.
Text almost illegible on Galaxy S4 The font size of the generated code on my Galaxy S4 is way too small to read accurately. I can find no way of increasing the font size.
Font too small to read code Galaxy S4 user. Ticket raised with Nexus Technical Support beginning of May regarding tiny font size of generated code. No update, just an acknowledgement that they were going to try and reproduce the fault.
Fixed an issue with activation from Google Chrome.
Saves power button by using proximity sensor for turning the screen on.
