If you suspect that someone is accessing your account, change all passwords of the account immediately.

Remember the 1&1 IONOS passwords for the following accesses:

  • 1&1 IONOS

  • 1&1 IONOS email accounts

  • 1&1 IONOS FTP

  • Since login credentials are often obtained by a virus on your computer, we recommend that you perform a complete virus scan of your computers. It is best to change your password again after the scan.

A selection of free online scanners can be found at, the website of the Association of the Internet Economy in Europe.
