It's actually worse than that. The very method with which fingerprints are stored is much weaker than passwords. Fingerprints cannot be hashed. By their very nature, each read of your fingerprint will be a little different, which breaks the hashing method. They can only be stored using encryption, which requires the same master password each time a new print read is compared to the stored key — a much weaker method than salted hashes. This more easily opens fingerprint credentials up to theft and brute forcing.
