What is a secret key?
BlockSurvey uses Stacks blockchain for Account / Identity Management.
The account you create is a Decentralized Identity(DID), which gets anchored in Bitcoin's blockchain through Blockstack.
A secret key is a set of 12 words that proves your ownership of our account/identity. It is used to access your identity on the Blockstack's blockchain.
Words, for example:
applied binge crisp pictorial fiery
dancing agreeable frogs light finish ping apple
