+/*
+ * TOTP face
+ * Time-based one-time password (TOTP) generator
+ *
+ * Generate one-time passwords often used for two-factor authentication.
+ * The secret key must be set by hand, by editing "totp_face.c".
+ *
+ * Available algorithms:
+ *  o SHA1 (most TOTP codes use this)
+ *  o SHA224
+ *  o SHA256
+ *  o SHA384
+ *  o SHA512
+ *
+ * Instructions:
+ *  o Find your secret key(s).
+ *      o Use https://github.com/susam/mintotp to generate test codes for
+ *        verification
+ *  o Edit global `credentials` variable in "totp_face.c" to configure your
+ *    TOTP credentials. The file includes two examples that you can use as a
+ *    reference. Credentials are added with the `CREDENTIAL` macro in the form
+ *    `CREDENTIAL(label, key, algorithm, timestep)` where:
+ *      o `label` is a 2 character label that is displayed in the weekday digits
+ *        to identify the TOTP credential.
+ *      o `key` is a string with the base32 encoded secret.
+ *      o `algorithm` is one of the supported hashing algorithms listed above.
+ *      o `timestep` is how often the TOTP refreshes in seconds. This is usually
+ *        30 seconds.
+ *
+ * If you have more than one secret key, press ALARM to cycle through them.
+ * Press LIGHT to cycle in the other direction or keep it pressed longer to
+ * activate the light.
