23andMe: An Unfortunate Update
I wish I had better news. Just after releasing a subscriber-only beta version of DNA Relatives Clustering, 23andMe technically has restored limited access to their chromosome browser, Advanced DNA Comparison. In October 2023, 23andMe removed Advanced DNA Comparison and Relatives in Common after becoming aware of a data breach. While 23andMe partially resurrected Relatives in Common some time ago, segment data downloads, the segment overlap (triangulation) indicator, and Advanced DNA Comparison had remained under lock and key. To some degree, they still are.
23andMe will only allow you to see the chromosome browser and the segment overlap indicator, what were once standard features, if and only if you have tested on 23andMe’s V5 chip for “Ancestry+Health” and have subscribed to 23andMe+. Even if you do that, “[y]ou can only compare your own profile (or profiles you manage within your account, or connected profiles) against your DNA relatives and connections.”
In other words, 23andMe’s non-subscribers who had been awaiting the return of the site’s most valuable tools must pay a ransom for a watered-down revamp. And even if you subscribe, one subscription only applies to a single profile. If you manage a multi-profile account and want to use Advanced DNA Comparison across all profiles, then it appears you must pay a separate subscription fee for each profile on your account. And each of those profiles must have tested on 23andMe’s V5 chip to be eligible for the subscription.
If this sounds impractical and unethical, that is because it is. As I mentioned years ago, many genetic genealogists tested their eldest living relatives on previous versions of 23andMe to capture and analyze endangered data. Now, some of those relatives are deceased; they cannot retest on 23andMe’s V5 chip, making those profiles ineligible for 23andMe+ subscriptions. The 23andMe V5 chip has lower compatibility with other older versions of 23andMe or even current versions of AncestryDNA or Family Finder, complicating cross-platform analyses on third-party websites such as GEDmatch. V5 also delivers less precise mitochondrial DNA haplogroups than previous 23andMe chips. From a genetic genealogy perspective, these facts make the V5 chip seem less desirable. And for those who tested on older versions of 23andMe, V5 is not an upgrade.
Ethics matter. Developing a new premium service with new premium features makes sense. But this is not that. This is revoking access to standard features that have existed since the late 2000s, diminishing their functionality, and then requiring users to endure yet another exploitative recurring revenue model all to get access to a less useful replica. That is categorically unethical. Given that 23andMe removed these features because of a data breach after placing several other standard features behind a paywall, this latest turn seems, at best, desperate, tone deaf, and extortionist.
23andMe claims that “The reintroduction of this tool isn’t just a simple ‘unlock’ of old software. We’ve rebuilt the engine using our enhanced HybridIBD™ technology.” But the value proposition does not justify the cost. And, in case you were wondering, users (regardless of their subscription status) still lack the comprehensive matching segment data download capability.
If you want immediate access to a chromosome browser without additional fees, then transfer your 23andMe raw data files to GEDmatch. Family Tree DNA’s Family Finder and Living DNA also allow free uploads; their chromosome browsers require a one-time fee for each profile.* Ask your 23andMe matches to transfer as well.
I sympathize with the customers who invested in this technology to find family, only to lose so many matches, so much data, and so much functionality to misplaced priorities.

*GEDmatch and Family Tree DNA allow law enforcement to practice forensic investigative genetic genealogy to identify persons of interest in criminal cases, but all users have the option to opt out of law enforcement matching. Read the terms and conditions and privacy policy of each site before taking action. Also, beware that certain forensic investigative genetic genealogy outfits, such as Othram, actively work against the terms of service of various sites, including GEDmatch, to access profiles that opted out of law enforcement matching.
