While I'm sure that I'm not the only person who believes in a trust-your-word based system, I'd include any Rites or Rites of Passage you undergo in your Biography, along with maybe a DM name who oversaw it, or a witness. (Since RoP ((Rites of passages)) are commonly overseen by a DM or ADM)
We have tokens on Ranks, It never really hit me that we'd need tokens for RoP's though... Good Idea in its' own way.
