In the recent past, some high profile companies have had user account details stolen by criminals. In some cases these details have been made public. Many people use the same usernames and passwords across different services, which means that their other accounts may also be at risk.
Runbox has not had a data breach. However, if you use one of the affected services and have used the same login with Runbox then your Runbox account could also be at risk.
We would suggest you update your Runbox password if you feel it might be necessary. What would have been a strong password a few years ago, might not be strong now. This is because criminals have an increasing ability to try large numbers of known passwords against accounts.
For useful tips about choosing strong passwords we recommend our Account Security help page. It is easier than you might think to create good passwords that are easy to remember.
To improve account security further, Runbox will be launching two-factor authentication (2FA) in the near future.
With 2FA turned on you will need to provide both your username, password, and an additional piece of information to access Runbox and your account settings. And if you choose to use IMAP, POP, or SMTP, you will be given strong passwords to use.
In the meantime, if you have any questions about account security, please contact us at Runbox Support.
