Set your new manual API tokens' expiry dates to 1 hour, 1 day, 1 month or leave them as they are: to never expire.
A couple of weeks ago we redesigned the security tab of your Bitrise account and made your manual API tokens separated from the automatic ones. From now on, if you generate a new token, you can choose its expiry date so you don't have to revoke them manually.
Go to your profile and select the Security tab from the left-hand menu. Click Generate new next to the Personal access tokens.

Once you generate a token you must save it to be able to use it:

After clicking Done, you can edit or remove any of your tokens as before and in addition, you'll see each token's expiry date too in the list:

Happy building!
