WD Passport External Hard Driver is not unlocking

I had fixed Bitlocker password in my 1 TB external hard driver. Everytime I was suppose to enter password after connecting the hard drive with PC for using but now it is not even accepting password credentials, can any one please help me to have recovery key of bitlocaker as that also I have missed. PLEASE URGENTLY HELP SOMEONE. Thnks

Since BitLocker is a Windows feature unrelated to Western Digital, then perhaps it would be best to contact Microsoft Support about this.

Encryption bypass is difficult since most companies would rather not have a backdoor exposed for exploit (If it exists), but they may be able to help you identify the reason why your credentials are not accepted.
