It happens: even with the login helper that CoachAccountable provides, sometimes your clients can’t get themselves logged into their account. As coach you always of course want to ensure your clients are having a great experience in all facets of working with you, so helping them get logged in is a natural thing to want to do.
First things first: make sure you haven’t deactivated their client account. By design, a client you deactivate CAN’T log in, so be certain that’s not the reason for their issue OR advise them appropriately if it is. (Assuming you deactivated them because your coaching relationship finished, this might be a good opportunity to invite them to start up work with you again.)
For security purposes the username and password of your clients are strictly their own, so you can’t let them know what they are or reset their password upon request. There are a few things you can do, though.
