Welcome to the community, @hitowabi! Please be informed that there are two servers (non-humanitarian server and humanitarian server) for KoboToolbox. If you have an account on one of the servers and try to log in to your account through the link for the other server, you cannot log in. So you’ll need to log in with the right link.
For the non-humanitarian account, try login through this link
For the humanitarian account, try login through this link
If you have password-related issues, feel free to reach us through support@kobotoolbox.org.
