Write down your passwords! Starting this morning, I've been trying to email myself some pictures from my phone so I'd have them on my computer. Since I was using an old phone (the pics were in relation to an insurance claim on my current phone that died last week) my gmail login info was out of date and I couldn't send any emails from said old phone. After awhile I couldn't figure out why my password wouldn't work, so I hopped on my computer and logged out of Google to try on there. Turns out I had forgotten that about 6 months ago my gmail was hacked and I changed my password, a password I now couldn't remember for the life of me. As of writing this I had been locked out of my email for about 8 hours and fighting with Google account recovery almost the whole time. I only just got lucky with that and regained access, but the whole time I could only get angry with myself for not physically writing it down somewhere. My head is still pounding from the frustration of potentially permanently losing my main and only email account.
Also add a phone line to your account and whatever other recovery options you can. In my case the phone wouldn't have done me any good since mine had died last week anyways, but you really don't realize how valuable this things are before you get locked out. I may have missed my 5:00pm deadline to get those pics sent in, but I learned a very important lesson, and Google sure doesn't make it easy to get back into your account.
