User Testimonials
"Usually, the mnemonic key is stored in the phone notepad. If I lose my entire cell phone, it will be useless, so I was wondering where to write this down for safety. I think it's really comfortable that you don't even have to write it down in the first place."
EK HAN
"Storing the mnemonic key in the cloud, or leaving my key intact, no matter how large a company is, was a bit anxious, but I can trust that it is key encryption and distributed storage."
