Users who have personal profiles set up on Institute of Physics are recommended to change their password for security reasons. See below from IOP:
Dear IOPscience user,
It has come to our attention that unauthorised access was gained by an unknown party to an IOPscience.iop.org server on 24 December 2016. This server contained a database which included your contact details and user password for IOPscience. We can confirm that no payment or other financial information was present on this server.
Please be assured that IOP Publishing places a high priority on data security and is taking this matter very seriously. We have already taken steps towards the prevention of any recurrence. We have engaged forensic IT specialists to investigate the incident and there was no evidence of access being gained to your personal information or any intent to gain such access. We therefore consider it unlikely that your personal information has been accessed, but as we cannot rule this out we wanted to bring this to your attention as soon as possible.
Even though we consider it unlikely that your password details have been compromised, we would recommend that you take this opportunity to change your current password for MyIOPscience and that you also change the password for any other sites or accounts that use that same password.
You can reset your password by going to the following link:
If you do not know your password, you can use the forgotten password tool available at:
