Will the push token expire if the app is not used?

Will the push token expire if the user does not use the app?

If it expires automatically, how many days should the app not be used before it expires?
Push tokens do not expire, but a token for a device can change under certain conditions (app deleted/reinstalled, device reset and/or restored from backup, some OS updates).

Apps should assume the token may have changed, and request a token everytime they are executed. If it has changed since the last time, they should update the push servers with the new token accordingly.
