Synchronizes account data (saved submission, saved comments, friends, subscriptions, settings) between two reddit accounts. This synchronization is one-way but also destructive; this means, for example, that if a submission is saved in the destination account but not in the source account, the submission will be unsaved in the destination account.
It's called "reddit transfer" instead of "reddit sync" because there's already a cool app called Sync for Reddit that you should try because it's really cool.
Copying preferences works for all preferences accessible via the API. Some preferences (e.g., those related to profiles) can't be controlled by the API. (Or maybe they can, I'm not really concerned with those settings so I haven't investigated it thoroughly.)
The script can handle accounts with two-factor authentication, too. Either way, you need application keys. For each account:
-
Open the Third-Party Authorizations page when logged in to your Reddit account.
-
Click the
create an app...button. Choose typescript, any name, and any redirect URL. -
Provide the provided client ID (in bold under the name you chose) and secret to
python reddit_transfer.py login $USERNAME.
Running Python 3.9:
pip install -r requirements.txt
python reddit_transfer.py login $OLD_USERNAME
python reddit_transfer.py login $NEW_USERNAME
python reddit_transfer.py transfer $OLD_USERNAME $NEW_USERNAME
MFA authentication may be broken. You can authenticate successfully if MFA is disabled.
