What to do if you're having trouble with Salesforce authentication

When logging into Tact version 1.6 or higher on Android, you'll be using your Salesforce credentials.  If you've already logged into Salesforce through Chrome on your device, Tact will log you in with that Salesforce account automatically.

If you happen to be logged into Salesforce in Chrome, but want to access a different Salesforce account with Tact, you'll want to log out of that account in Chrome and clear your Chrome history before logging into Tact with different Salesforce credentials. 

If you get an Oauth error when trying to log in to Tact, please follow the steps below to clear your Chrome history on your mobile device and then you should be able to log into Tact with your preferred Salesforce credentials.

1. On your Android device open the Chrome app and at the top right, tap the 3 dot icon.

2. Tap on History 

3. Tap on Clear browsing data.

4. At the top, choose a time range. To delete everything, select All time.

5. Next to "Cookies and site data" and "Cached images and files" check the boxes.

6. Tap Clear data.
