Co-ordinate to the study: "Ii participants changed their Yahoo! passwords twice, once after each alienation announcement. 2 participants changed their password on the breached domain within one month of the alienation annunciation, a full of five within ii months, and eight inside three months."

The research too looked at the quality of new passwords, discovering that but ix of the 21 people who changed their passwords opted for stronger passwords. Meanwhile, 12 created weaker or equal-strength passwords.

In terms of countersign strength, the research claims: "On average, participants created new passwords that were 1.3× stronger than their old passwords after transforming force on the log10 scale."
