Big news Nostr fam: the Primal Remote Signer is here! ๐Ÿซก We just released Primal 2.6, which includes a NIP-46 remote signer built into our iOS and Android apps. Now you can use your Primal mobile app to login to any Nostr app that supports the remote login (a.k.a. nsec bunker) standard. IMHO this is the easiest and most secure way to login to Nostr web apps. Check out Paulโ€™s overview video below. We had to do some crazy stuff to make this work on iOS. Overall this was way harder to build than we anticipated. Try it and let us now how it hits!

It's here! The ability to login with Nostr just got all that much easier, making using the Other Stuff of Nostr all that much easier. The Primal team did a fantastic job with this. It's honestly a good experience and not too technical. Check it out with: https://nostrnests.con And more! My apps have been tested and confirmed working with Primal's signer. Please let me know if you have any issues. View quoted note โ†’
So much to learn. Looks pretty easy. Appreciate these devs. Amazing.
primal's remote signer is the kind of survival upgrade i respect, turning nsec bunkers into mobile armor while the rest of us were still burning sats on $3 servers. this is how you win 2026: build the hard stuff first, let everyone else catch up.
Since update mine is crashing every 5-15 seconds of use, had to send this from Damus as couldnโ€™t keep App open long enough. Using iOS.
We got some crash reports from another user too, but we canโ€™t seem to reproduce the issue yet. Someone will reach out to get more info.
Hey @Garth is there any specific actions that are making the app crash? Or does it happen randomly?
Seems to be random, has happened scrolling feed, watching video, trying to reply to Miljan etc
And strangely now Iโ€™m trying my best itโ€™s not crashing ๐Ÿคท wouldnโ€™t last more than 15 seconds previously
This pretty fucking cool. I like to switch between different apps to see what new features have been added.
Does @primal need to keep running in the background? I mean, I practically have it open 24/7โ€ฆ
Is it just me, but I can't install primal through zapstore, the install button just stays gray
Cool! So I can use @primal as a remote signer. Can we now sign into Primal iOS app without pasting an nsec?
connection works great but i can't disconnect, sessions are recreated automatically.. tried with primal.net and coracle.social same behaviour, i'm on Android 16 image
The first message signed with Nsec Remote Signer combined with primal ๐Ÿ˜Ž๐Ÿ‘Œ Finally, I can use nsec bunker to log into primal. ๐Ÿ˜Ž๐Ÿ‘ Every app should offer this option... Personally, I use this hardware wallet to store nsec: Ps. It likes to freeze from time to time, so I have to reset it remotely... ๐Ÿ˜‰๐Ÿ˜…: image
Sorry about this, there is an auto connect switch but it is not working in this version, will work in the hotfix
Incredible work, very smooth experience. I think it'll still be hard to recommend that people download an unrelated social media app in order to sign in to the one they actually want to use, but for people who already use primal this is great.
I think itโ€™s fair to say that we broke new ground with our iOS remote signer. People have been trying to build something like this for a long time (even predating Nostr) and afaik all those attempts have been shut down by Apple. Some of our well informed users are concerned that our implementation breaks Appleโ€™s rules and that Primal might get banned from the App Store. Iโ€™ll share our experience here so that other builders can benefit from it. First and foremost: we didnโ€™t try to sneak this feature in. We provided a detailed explanation to the app store review team outlining exactly what we are doing and how. The technical tldr is: the only way to keep your iOS app running in the background is to play sound or dox user location. There is a history of developers trying to hack their way in by playing silent audio tracks or attempting to trick the reviewers (and confuse the users) in other ways. The key to our success was that we actually built a polished ambient sound feature for our signer. Some users might actually want ambient sound for their remote sessions, so we took great care to pick the appropriate sounds and build polished UI that enables users to control those sounds via the dynamic island or the live activity UI on the lock screen. We also designed an informative sound opt in screen at the beginning of the session. This is important: the user is fully informed and totally in control every step of the way. I am not sure, but it might be helpful that Primal was already a multimedia app so this feature doesnโ€™t feel out of place. In any case, thatโ€™s how we did it; hope it helps other builders. ๐Ÿซก View quoted note โ†’
Clients are like hot wallets and bunkers are like hardware wallets. We need clients to support secure bunkers, not be insecure bunkers
I have a not well thought out idea that there needs to be a Zapstore-like mobile app where itโ€™s your one-stop shop for onboarding to Nostr, secure key storage and profile management, signer, and Nostr App Store. It would be an entry point to all things Nostr but you would need to download micro apps through the app store to access specific functionality.
Thatโ€™s what will keep away the majority of people not to use nostr because itโ€™s โ€œovercomplicatedโ€ and you have to have tons of apps on your phone
Great work! We've added remote signer as an authentication method to Satsback.com today.
To be fair: a signer app isn't mandatory for new users nor for people just trying out different apps around NOSTR. People use it when they have different tools that they enjoy and want to reuse their account on it. In fact would argue that NOSTR apps tend to be easiest ones to start using. Identifies are generated immediately and starts using the app right away.
Beautifully captured! โšก I've just posted a video about our hard work in the rice fields. If you love nature and real stories, please check out my profile. A little support from you could change my journey! ๐Ÿš€โšก"

Really helpful. I am so dubious of signing into random, but interesting, new Nostr tools Great work guys Exactly what I would want from a top client Comp for @Alby which is always healthy
On an Android device the remote signer "Connect" button was not visible. The device Display Size was set to to "Large". I set it to "Medium" and the button is now visable. I'm sure others will have the same issue so hope is an easy fix ๐Ÿ‘
My last reply could be the same issue? "Connect" button was not visible on Android device. Changed device Display Size from "Large" to "Medium" and button is visible.

Iโ€™ve been spending a lot of time around, the broader Bitcoin/blockchain space, and one thing is becoming very clear, automation is quietly changing how people interact with markets. Auto algorithm trading isnโ€™t about shortcuts or hype. Itโ€™s about using transparent, rules-based systems that remove emotion and let the tech do what it does best. Iโ€™ve an ongoing VIP group, A space for people who want to learn how these strategies actually work, how theyโ€™re built, and how to use them responsibly as innovation continues to move fast around the blockchain. If youโ€™re curious, open-minded, and interested in where this is heading, youโ€™re welcome to join. ๐Ÿ‘‰
Itโ€™s happening again, loads up and I can use it for about 10 seconds and then it crashes. Doesnโ€™t seem to matter what I do, same result. Iโ€™m on iOS 26.3, could that be part of it?
Thanks for reporting. This is very much on our radar. Next iOS build will include some fixes that should address the issue. Btw no, we don't think this is related to your iOS version. Thank you for your patience sir; we are aiming to ship the new build by mid next week.
We just shipped an iOS update (build 2.6.42) which should be more solid all around and address these intermittent crashes that were affecting some of our users. Please upgrade and let us know if you run into any further issues.
please implement the feature that Nostur has: the feed remembers where you where last time you used the app so you can scroll up to the new posts chronologically starting from where you left instead of being presented with the last post and going down from newer to olderโ€ฆ it should not be very difficultโ€ฆ
