What is the best practice in naming your "user" table?

Here's three best practices I try to follow when naming tables:

• Never name a table with plural (such as "users")
• Never name a table using a reserved keyword (such as "user")
• Never prefix your table name with "tbl" or some other object type prefix

Keeping all this in mind, how do you recommend naming the table that will hold user identities?

I agree, do not use any reserved words, or quoted or bracketed or escaped forms of reserved words.

• Name the User table Person.
• If you really, truly, absolutely must use a reserved word, do this:
  • Userr
  • Passwordd
