You can also head to /login/forgotpass on your Solverboard instance. (So if your Solverboard is located at https://www.organisation.solverboard.app/, you'd go to https://www.organisation.solverboard.app/login/forgotpass .
If you've forgotten your Solverboard web address, ask your Organisational Admin.
If the reset doesn't work, you don't get an email or need further help, get in touch with us.
