You should change your Slack password if you were using the app on Android, as per the email sent by the company. Apparently, from Dec 21 to Jan 21, the Android version of the Slack app stored user credentials in plain text, which in theory means any other apps on your phone can access them.
All Slack users should update their password as soon as possible
If you have a popular communication tool installed on your Android phone, the first thing you need to do is update it to the latest version from the Play Store, as changing your password won’t do any good if you’re still using the old version.
You may have received an email from Slack, you can click the link to change your password. Otherwise, you will have to reset your password from your desktop computer using Slack instructions.
Slack users should update or Reset their password
- First, sign in to Slack
- On your desktop, click your profile picture.
- Select View profile from the menu.
- Click More, then select Account settings.
- Next to Password, click Expand. If you do not have such an option, your organisation needs single sign-on (SSO) to sign in to Slack.
- Next, reset or change your password.
If you have misremembered your current password, you can reset your password by email, and slack will send you an email including a link for resetting the password.
If you remember your current password, submit your current password, then enter a new password. Then, click Save to finish.
Of course, if you’ve used your Slack password on other websites, you should change your passwords for them too (preferably something unique).
