Glide Identity's three-carrier beta: what the data does and doesn't show
What the sources establish about the Aug 3, 2026 announcement, and the coverage, pricing and security questions they leave open.
[EDITORIAL: sample briefing drafted with AI assistance. Verify every claim against its sources before launch.]
BLUF The sources establish that Glide Identity announced a beta of SIM-based cryptographic authentication across AT&T, T-Mobile and Verizon on Aug 3, 2026, and that trade and general press covered it. They do not show which devices, operating systems and plans work, how often fallback triggers, what it costs, or how it holds up under independent security review.
Moderate confidence
The announcement and its date rest on the company's own release, corroborated by trade and general press. The gaps are established by their absence from our sources, which could change if the carriers or the company publish more.
Key points
- The Aug 3, 2026 announcement names AT&T, T-Mobile and Verizon, and the release quotes a Verizon Business executive.
- Everything about how the product works comes from the company. We found no independent security assessment.
- Device, OS and plan coverage, fallback rates and pricing are not published in our sources.
- Number verification, which Aduna announced with the same three carriers in July, is a different check.
What was announced
On Aug 3, 2026, Glide Identity announced a beta of what it calls "carrier-native cryptographic authentication" across AT&T, T-Mobile and Verizon. The release, distributed on Business Wire, includes a quote from a Verizon Business executive.[1] Biometric Update covered the three-carrier launch on Aug 7,[2] and on Aug 23 Fox News' CyberGuy featured Glide in a piece on SIM-based bank login as a replacement for SMS one-time passcodes.[3]
The product behind it, MagicalAuth, replaces SMS codes with verification through the mobile network, according to the company. Glide says it "confirms identity using the SIM's cryptographic link to the network" and completes authentication in under one second with no codes.[4]
What the data shows
| Question | What our sources show | Kind of source |
|---|---|---|
| Was a three-carrier beta announced? | Yes, on Aug 3, 2026, naming AT&T, T-Mobile and Verizon | Company release, covered by the press |
| Did a carrier speak to it? | The release quotes a Verizon Business executive | Company release |
| Is the company in the relevant industry bodies? | FIDO Alliance member at Sponsor level; listed as a GSMA Open Gateway partner | The bodies' own listing pages[6][7] |
| What came before? | A Series A of more than $20 million on Oct 13, 2025, and selection as one of 10 finalists for the RSAC 2026 Innovation Sandbox contest | Press, company releases and the organizer; see the dossier timeline |
The dossier also runs a computed check of CISA's Known Exploited Vulnerabilities catalog for any vendor matching "Glide", recalculated every time the site is built.
What the data doesn't show
- Coverage in practice. Our sources do not say which devices, operating systems and plans work in the beta, or how often fallback triggers. Glide says that when a device or OS doesn't support SIM authentication, it automatically switches to alternatives such as passkeys or email links.[4]
- Independent assessment. We found no independent security assessment in our sources. Everything we know about how the product works comes from the company.
- Standards treatment. Our sources do not address how NIST SP 800-63B-4 would classify SIM-based cryptographic authentication. Our NIST briefing covers how the guidelines treat SMS codes.
- Commercial terms. Pricing is not published, the developer documentation requires a login, and carrier contract terms are not in our sources.
- SIM swaps and eSIM transfers. The company positions the product against SIM swap. We have not verified how it handles SIM swaps or eSIM transfers at the carrier. See SIM swap attacks, explained.
Number verification is a different check
On Jul 8, 2026, Aduna, a network-API joint venture, announced number verification with the same three carriers.[5] Number verification, a CAMARA API, confirms that a request comes from the SIM tied to a number. Glide describes its approach as SIM-based cryptographic authentication. The difference matters, and our carrier authentication primer sets out the approaches, but Telemetry has not independently tested either.
Other companies offering network-based or SMS-alternative verification include Prove, Twilio, Vonage, Sinch, Infobip, Telesign and IPification. For where regulators stand on SMS codes, see the SMS OTP regulation board.
What would change this assessment
- Carrier-side documentation of the beta.
- Published device, OS and plan coverage, or fallback rates.
- An independent security assessment.
- Published pricing.
Questions
Which carriers are in Glide Identity's beta?
AT&T, T-Mobile and Verizon, according to Glide Identity's Aug 3, 2026 release.
Has Glide Identity's authentication been independently tested?
We found no independent security assessment in our sources, and Telemetry has not tested it.
Is this the same as carrier number verification?
No. Number verification confirms that a request comes from the SIM tied to a number. Glide describes its approach as SIM-based cryptographic authentication.
