This article talks specifically about Google Workspace accounts. If you're using a personal Gmail account (.e.g your email address ends in @gmail.com) this does not apply.
Google Workspace accounts will ask for users to re-authenticate every 2 weeks by default - you can find out more about this here. If you're a Google Workspace admin or just a user of a Google Workspace account, some different options can help you log back in quickly...
If you're a Google Workspace admin, it's possible to change this behavior by specifying the duration of web sessions for Google Services as per the Google Help article here. This will change the session length for all your Google Workspace users, across all web sessions (not just for Wavebox).
If you're not a Google Workspace admin or are unable to change the session length, we recommend using the password manager that Wavebox includes and electing to save passwords when logging into sites, or alternatively, using one of the password manager extensions available in the Chrome Web Store. This will ensure that when you are logged out, you're able to sign back in with the least hassle possible.
