Gmail Error: Password not accepted from server [SOLVED]

Found a good solution today if you’re receiving the following error:

SMTP -> ERROR:Password not accepted from server. Code: 535 Reply: 535-5.7.1 Please log in with your web browser and then try again.

Even if the Gmail account credentials are correct, Google’s servers may still block the server attempting to authenticate (more than likely due to a new server location and/or recent password change).

Firts, you need allow a sign-in attempt from your device:  https://myaccount.google.com/security#activity

To get around this, make sure you are logged in using the same Gmail account in your browser, and then simply open the link below and step through the process of verification:

https://accounts.google.com/b/0/DisplayUnlockCaptcha

This will allow access to your Gmail account for about 10 minutes so that a new authenticating server can be detected.  Be sure to try authenticating again within this time period.

Your mail app might not support the latest security standards. Learn how to allow less secure apps access to your account. https://www.google.com/settings/u/0/security/lesssecureapps
Make sure your mail app isn't set to check for new email too frequently. If your mail app checks for new messages more than once every 10 minutes, the app’s access to your account could be blocked.
Try changing your password according to our tips on creating a strong password.
If using CPanel(WHM)

Cracking password Oracle 12c format using hashcat

1. Download hashcat from https://hashcat.net/hashcat/ and unpack it
2. Select spare4  value from sys.user$  
   In this case for example, System Properties:
   -> Database: Oracle 12c
   -> Account: SYS
   -> Passwd: SYS
   -> SYS.USER$: NAME = 'SYS', SPARE4 = 'S:B283DCCE5DC81D2023E3304C8818646CFF434C9C2FCDD505130ED13524B4'
      This means: HASH = 'B283DCCE5DC81D2023E3304C8818646CFF434C9C', SALT = '2FCDD505130ED13524B4'
   The format is [hash 40 "chars"]:[salt] , example B283DCCE5DC81D2023E3304C8818646CFF434C9C:2FCDD505130ED13524B4
   then put in to file hash_salt.txt
3. Run the following hashcat command with m = 112 (Oracle 11g /12c) 

c:\hashcat-2.00>hashcat-cli64.exe -m 112 -a 0 -o result.txt hash_salt.txt dict.txt
