Verify your download

A fingerprint only helps if you check it. Compute the SHA-256 of the file you downloaded and confirm it matches the value shown on its card. A match means it's the exact build we published, not a modified or repackaged copy.

# macOS & Linux
shasum -a 256 ~/Downloads/Lockday-<version>.dmg

Each release also ships a SHA256SUMS manifest, so you can verify everything at once with shasum -a 256 -c SHA256SUMS.
