PIPEDA Findings #2021-005: Staying signed in by default to email services poses serious privacy concerns for users accessing their email on a public or shared computer
This investigation concerned Yahoo! Canada's "Stay signed in" feature for its email service, which defaulted to keeping users logged in. The OPC found this practice posed significant privacy risks, especially on public or shared computers, as emails can contain highly sensitive personal information. Yahoo was found to have inadequate safeguards and failed to obtain meaningful consent for the disclosure of personal information that could result from this default setting. Yahoo committed to changing the feature to an opt-in basis and providing clearer warnings to users.
