Damn. I changed the unlock pattern on my Nexus 7 and stupidly locked it “to test” the code. Unfortunately I got it wrong each time and now my inbox has 20 emails from Cerberus with pictures of the top of my head and occasionally my eyes.
Panic! Luckily there is a way out. Fail enough times and the device asks you to login to your Google account. It’s supposed to appear after 5 or 6 attempts but I have the 20 Cerberus emails and the “Forgot pattern” message did not appear that quickly.
Nothing easier than logging into Google which I try but it says my email or password are incorrect. I try again. No, nothing. Then it hits me. Two step auth. I had to generate a new application specific password. That worked!
A few minutes later and there’s a notification warning me my Google login has failed. After using an application specific password on the lockscreen I had to login again using my real password. Weird.
tl;dr If you have two step auth enabled use an application specific password to login to Google if you forget your Android unlock pattern. Breath again.
