Clef, an authentication client that combines several solutions for problems posed by centralized systems, continues gaining ground. Initially launched in early , its appeal has recently inspired a partnership with AlphaPoint, a lead provider of cryptocurrency exchange software.

What similarities do these systems really bare, though? This not only negates the risk of a hacker stealing passwords from the server, but also avoids any need for transmitting the private key analogous to a password during authentication, thus further protecting users from hackers that might try to intercept their communication.

Instead, RSA cryptography uses a hash function to incorporate verifiable information about the private key into a message — called the signature — which the user then sends as proof of its identity. Unlike databases that use passwords, the source requesting authentication does not rely on an identical copy of the private key for verifying this signature.
Instead, the source uses a public key — hashed from the private key — to provide a means of verifying the signature without the key needed to generate it. To protect users from identity theft if their device gets stolen, Clef implements a second authentication factor: it uses fingerprint recognition by default, and falls back on a PIN number in cases of devices that lack biometric identification.
Fear hardware loss? No need.
Clef also generates a unique signature with each login, which expires within seconds; this rapid invalidation of the signature deprives attackers from potentially useful information. Clef also subtly implements a further factor regarding location, in an attempt to combat phishing. After this brief initial confirmation, logging in proceeds as normal without the extra step.
Perhaps most importantly, though, Clef offers all these aforementioned features free of charge, helping assure its popularity and a large user base. Press Releases. Learning Bitcoin.
