Go check your Gmail secondary email now, or some day you'll be locked out of your email for five days
That's what's happening to me. Maybe someone figured out my password, or maybe it's a technical glitch, but my Google password has been changed. I joined Gmail in college, so I used a school address as my secondary address. Years later, I finally need that password-reset email but the address is long dead. And Google's policy is to make me WAIT FIVE DAYS while someone could be wreaking havoc on my life before I can answer my security question and get my email back.
CHECK YOUR SECONDARY EMAIL NOW. Make sure you can access it if you ever lose access to Gmail.
And if someone named popsnap@gmail writes to you, it might not be me.
