Since the Cloud has been proven to be so vulnerable (cf. the attacks/breeches/failures witnessed these past few months) using a decentralized system to store my passwords was crucial. This is the first thing that made me turn to Myki. Myki even auto-fills out the 2 factor authentication.
Then I discovered a whole lot of other useful features that help me manage and store my passwords efficiently. One of them being the sharing center, that offers an easy way to store, share and track shared accounts (and revoke them too!) We can now add credit cards and myki helps autofill them securely while making an online transaction.
I've been happily using it for the past 8-9 months, and definitely advice everyone to give it a shot.
