Per this answer, configuring
defaultTokenDuration is the way to change the lifespan of hidden entries' share links from the default 24 hours. The v2 docs describes this as affecting "system tokens" but no further explanation of system tokens is provided. The v3 docs refers simply to "tokens."
[edit: I believe one other thing this controls is the lifespan of password reset tokens.]
I'd like to increase the lifespan of draft entries' share links, but wonder what other consequences I should take into account before changing
defaultTokenDuration. What all does it affect?
