Do the LIFX personal access tokens expire and if so what is the time to live for them?
As far as I have seen they don’t expire, but it you’re automating the tokenization process it might pay to have them refresh every month or so. The ones you manually generate from your LIFX cloud settings screen don’t expire.
LIFX access tokens obtained as personal access tokens or via an OAuth handshake do not expire. However they may be revoked by the user at any time.
