Abstract
Triple-tap password entry is described. In an embodiment, a password is received as a sequence of characters that are each entered as one or more keypad inputs, such as with a television remote control. The keypad inputs for each of the characters are displayed as the sequence of characters are received, and a character of the password is obscured after the character has been received such that the characters are consecutively obscured to conceal the password. A character of the password can be obscured when a subsequent character is received, or when a time duration of the character display meets and/or exceeds a time limit.
