While changing passwords, remember to use a unique one and do not use the same password that you may use on other platforms or banking sites. Go to your Slack profile, tap on More and then Account Settings.
Also, clear the cache of the app and update to the latest version of the Slack Android app from Google Play. If you wish, you may want to uninstall the older app and proceed with a fresh installation as well.
Not to forget, if you have repeated the password that you had for Slack on other platforms, then change the password of those websites or apps too. Remember, your password may be there out in the wild and it could be used by unwanted people to access accounts of others platforms.
Last month, Slack faced a downtime and users faced connectivity issues with the platform. More than 15,000 users had initially reported issues, according to outage tracking website Down Detector. The messaging app had over 142,000 paid customers at the end of third quarter.
