Authentication Failed: Invalid Credentials error while using SMTP or IMAP services

0 votes

I created a RPA bot usimng Uipath and wanted it to read mails from gmail and also send mails to my gmail account, but every time I am running the code I'm getting this error- 'Authentication Failed'. Sometimes it says Invalid Credentials, but I am putting the right credentials for my gmail login.Please help, if anyone knows how to resolve this issue?

Hi @Smita, you are facing this problem because Gmail allows highly secure transmissions and blocks any app which tries to access or send mails to gmail. So to resolve this error, try allowing the 'Allow Less Secure Apps' feature in security settings of your google account. 

Go to this link https://myaccount.google.com/ and click on  'Security'. Then scroll down and navigate to 'Less Secure App Access'. Now click on 'Turn On Access'

Now run your bot and try sending or receiving email. I hope it will work.

I have done this too but still, it is showing bad credentials.

Hey Rimjhim, in the Server name are you putting smtp@gmail.com or smtp.gmail.com? Can you please share the screenshot of your workflow?
