Problem
Blockchain creates various percieved issues for users regarding account management and passwords. Due to the underlying logic of truly decentralized technologies, resetting passwords in purely decentralized applications is absolutely impossible as there is no central authority to allow that technically – which means losing a password results in being unable to access the user account ever again. All the information and value storage, like holdings of cryptocurrencies, will be inaccessible to the owner. Therefore, all services and apps have to be very transparent about this issue (as it can be a huge risk, especially for newcomers in the field) and help them with overcoming it.
Solution
An example for such a thing would be “never eat sea-weed” for remembering the directions north, east, south, west. In the context of passwords, this technique can be used to make passwords easier to read, manage, store, and memorize. This might make it more convenient to users, as managing a string of words is simpler than managing a long chain of random characters.
Connected patterns
Resetting a lost password via email is an alternative when it is possible to sacrifice security and partially centralize an otherwise decentralized application.
