    1. CO**Do not store passwords in plain text**. Reversible encryption is (almost) no better. You _need_ to understand what hashing means.

    2. COAre the passwords encrypted or are they hashed? Encrypted passwords will need to be decrypted using the proper key(s). If the password is hashed, then you will be unable to send the user their password. Instead, you must ask the user to create a new password.

    3. COSecurity is **hard**. Do not re-invent the wheel. Use an existing, proven, authentication package.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
