Copying your words into your phone seems sensible. It is one of the most common ways that crypto gets stolen. This guide is part of our seed phrase backup guide.
Why digital storage is the problem
A hardware wallet exists to keep your keys away from internet-connected computers. A digital copy of your phrase undoes that entirely. Your words now sit on devices and servers that you do not fully control, and you may never know if they were copied.
The common options, and how they fail
| Method | How it fails |
|---|---|
| Photo | Syncs to the cloud, read by malware, and image text can be searched |
| Screenshot | Same as a photo, and often overlooked |
| Notes app | Synced, and stolen if your account is hacked |
| Email or drafts | Exposed if your email is hacked |
| Cloud drive | Anyone in your account can find it |
| Password manager | A hack of your vault or device exposes it |
| Text file | Infostealer malware searches for these |
| Messaging apps | Stored on several devices |
| Printer | May keep a copy, and on a network |
Why a password manager is different for this
A password manager is a great home for passwords, because a stolen password can be changed. A stolen seed phrase cannot be recovered, and the thief can act in seconds, with no second factor. See why crypto's master password is different.
But what about loss?
Digital copies feel safe because they do not burn. The answer is more offline copies in different places, not a digital one. See how many backups you need and metal backups.
Can encrypted digital backups work?
Advanced users do sometimes encrypt a backup, but it adds real risks: the phrase is exposed while you do it, and a forgotten password means losing access. Read encrypting a seed backup before you try. For most people, it is not worth it.
What to do if you already stored it digitally
- Treat the phrase as compromised.
- Set up a new wallet, ideally a hardware wallet, with a new phrase.
- Write it down on paper, and do not photograph it.
- Move your funds to the new wallet.
- Delete the old digital copies. Remember the trash, cloud backups and other devices.
Do not just delete the photo and carry on. It may already have been copied. Our guide to an exposed phrase explains what to do.
