Emergency sign in with security questions.
Recently I had all my valuables stolen while travelling (again!).
When this happens you are automatically lockef out of Yahoo mail, because you need your phone and computer to sign in from a new device or country. The thief who had my tablet, phone, money and credit cards, also had access to my email and Facebook accounts, while I didn't.
In a country where I didn't speak the language, I couldn't contact anyone. Friends and family may have helped, but instead they just became distressed when contact ceased abruptly, and I didn't answer messages.
Luckily the police finally found me a station where someone spoke a bit of English. He was able to give me my credit card's toll free number, and they sent some cash within a couple if days. My hotel took most of it for the missing key, and I used the rest to buy this cheap phone. But, as with local internet cafes, the whole screen was in a different language.
Without the help of a sales assistant who spoke English and let me use his account, I don't know what I would have done.
All my forward bookings and related information had been sent by email, and needed to be active for me to check in etc. I was also in the middle of some important business negotiations, which were then stalled. It took a full week from my holiday, just sitting in my hotel trying to get everything back on track.
With emergency email access most of this wasted time and added trauma could have been averted.
I would also have had more peace of mind if I could secure my accounts with security questions. If the thief could read English, he still technically has access to all my info, including bank statements etc. Anything that has been emailed to me, and all my contacts.
Think about how you would cope in this situation. It takes precious days to organise your life again, while someone else has free reign with your info.
