E_ADEPT_RESET_PW_REQUIRED when attempting to create a ByteBooks ID from an existing Adobe ID

Refer to article "Adobe eBook Platform Transition and Adobe ID Sign-In Changes -- ACS and RMSDK in 2026 and Beyond"

Problem:

Unable to login using a ByteBooks ID resulting in the error message:

E_ADEPT_RESET_PW_REQUIRED
USER_ALREADY_EXISTS

The account appears to be in a corrupted state where the user cannot register, login or reset the password.

Possible Causes:

The Adobe ID has already been registered with Wipro. 

• E_ADEPT_RESET_PW_REQUIRED indicates that the ByteBooks password needs to be set/reset
• USER_ALREADY_EXISTS indicates that a ByteBooks account already exists for the email address

Solution:

1. Open an Incognito/Private Browsing window
2. Go to https://dtsbytebooks.com/transition-help
3. Select "I have an existing Adobe account to migrate"
4. Make sure to use the same email address that was associated with the Adobe ID
5. Complete the migration process and set a ByteBooks password

Once the migration is complete, please sign in to Adobe Digital Editions using the newly created ByteBooks ID and ByteBooks password.
