From > Encrypt and protect a storage device with a password in Disk Utility on Mac - Apple Support


"When you format an internal or external storage device, you can encrypt and protect it with a password. If you encrypt an internal device, you must enter a password to access the device and its information. If you encrypt an external device, you must enter the password when you connect the device to your computer."


Eject and disconnect the external drive.

Then reconnect the external drive to your computer.

Does it not ask for the password when reconnected to your computer?
