/*
* TOTP-LFS face
* Time-based one-time password (TOTP) generator using LFS
*
* Reads from a file "totp_uris.txt", containing a single secret key in a
* series of URLs. Each line is what's in a QR code, e.g.:
* otpauth://totp/Example:alice@google.com?secret=JBSWY3DPEHPK3PXP&issuer=Example
* otpauth://totp/ACME%20Co:john.doe@email.com?secret=HXDMVJECJJWSRB3HWIZR4IFUGFTMXBOZ&issuer=ACME%20Co&algorithm=SHA1&digits=6&period=30
*
* This is also the same as what Aegis exports in plain-text format.
* This face performs minimal sanitisation of input, however, and you
* will only see errors if you use the simulator or view the serial console.
*
* At the moment, to get the records onto the filesystem, start a serial connection and do:
* echo otpauth://totp/Example:alice@google.com?secret=JBSWY3DPEHPK3PXP&issuer=Example > totp_uris.txt
* echo otpauth://totp/ACME%20Co:john.doe@email.com?secret=HXDMVJECJJWSRB3HWIZR4IFUGFTMXBOZ&issuer=ACME%20Co&algorithm=SHA1&digits=6&period=30 >> totp_uris.txt
* (note the double >> in the second one)
*
* You may want to customise the characters that appear to identify the 2FA
* code. These are just the first two characters of the issuer, and it's fine
* to modify the URI.
*
* 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.
