 When using a KDF for cryptographic operations always ensure to use a recommended and approved KDF properly according to the latest recommendations and the software provider's documentation. E.g Only using a key derivation functions that is constructed from hashes against which no non-trivial pre-image or length-extension attacks are known and where attacking the key derivation function directly is infeasible. Using user-supplied input together with HKDF will make it easy for password crackers to execute a preimage attack.
