Thanks — regarding how long LiveKit tokens are valid: • Token validity is set by the JWT

exp

claim (a Unix timestamp). That determines when a token becomes invalid. • Typical TTLs range from about 10 minutes to 1 hour, but you can set any expiry you need when generating the token. • Token expiry is checked at connect time. Once a participant is connected, LiveKit can refresh tokens to maintain the session. • Also watch

nbf

(not before) and avoid zero/negative TTLs (those expire immediately). If you’d like, tell me how you’re generating tokens (language or SDK) and the TTL you want — I can show the exact code snippet to set

exp
