Wondering how to do this if everything is encrypted? Here's an idea: create a separate password database. Put all the important main passwords for your computer, phone, other password databases and also for your backup archives in this database. Now create a list of 10-20 personal questions that only you can answer. The answers to the questions together form your master password for emergencies. Copy this critical database to a USB stick and store the questions next to it. If you want, you can also work through the questions together with your partner, friends or family members. This way, you can recover your data even if something should happen to you.
