Two things can play a role here:

1. The password must meet the requirements that you see listed: at least 8 characters, lowercase and uppercase letters, numbers and a punctuation mark. For a punctuation mark only use the following four characters: ! or @ or $ or %. Other characters, such as underscores or connecting lines, give problems.
2. Further below you must enter the password again for verification. This is sometimes overlooked, because this field is a bit hidden behind the text mentioned above about the requirements regarding the password. Navigate to the second field with the mouse or the tab key.

If you have a different phone or have put the phone back to factory settings, then the activation process must be partially follows again. The physical telephone itself is connected to the app at IP address level. In this situation call our office to have your account reset “hard” (00 31 70 313 3000) or send an e-mail to payroll@interfisc.nl. You can also do this yourself, but that is quite complex.

When we have reset the account hard for you the connection at IP address level is removed. You will receive a new e-mail from Unit4. With this e-mail and the Quick Guide (available at www.interfics.com/login) you follow the activation process from making a new password (from step ⑤). Note: the password must be different from the old passwords. This can be done by changing a letter or a number, for example.
