    # What level of device verification should be required from users?
    #
    # Valid levels:
    #   unverified - Send keys to all device in the room.
    #   cross-signed-untrusted - Require valid cross-signing, but trust all cross-signing keys.
    #   cross-signed-tofu - Require valid cross-signing, trust cross-signing keys on first use (and reject changes).
    #   cross-signed-verified - Require valid cross-signing, plus a valid user signature from the bridge bot.
    #                           Note that creating user signatures from the bridge bot is not currently possible.
    #   verified - Require manual per-device verification
    #              (currently only possible by modifying the `trust` column in the `crypto_device` database table).
