There are different reasons that your password may not work when authenticating/logging in.
Review the following points for carrying out proper authentication on LonelyID:

• Be sure that you activated the LonelyID key in your mobile when you registered. During your key’s registration process, we sent you a welcome email containing an activation link. You must open the email we sent you and click on the link it contains. If you no longer have the email we sent you, do not worry. Just fill out the form in LonelyID Mobile again, entering your identifier and the same email address that you used the first time. Your password will be generated again and you will receive another email so you can confirm activation.
• If your mobile’s LonelyID key was already activated but the password continues to not work, try syncing the LonelyID Mobile app (You can read 'Synchronize (LonelyID Mobile)' to learn more about the syncing process.
• Check that the password you have keyed in remains valid when performing the authentication. The password changes its value at specified moments. Try to copy the password when it is shown in black. When the password colour changes from black to red, this means that it is about to change. In this case, it is better for you to wait for a new password to be generated in order to login correctly (You can read 'Where is my password?' for more information).
