Is a 12-Word Seed Phrase Really Safe in 2025? | Expert Views Update
A growing number of people are questioning the safety of 12-word seed phrases, especially compared to the safer standard of 24-word phrases. While some maintain that 12-word options are adequate, a wave of recent comments reflects ongoing concern about their true security in today's rapidly evolving technology landscape.
The Debate Over 12-Word Phrases
With claims of safety circulating, some argue that using a 12-word recovery phrase can still be secure. One user stated, "A few minutes of keying in some words could save your bag; you never know what will happen." However, many others continue to express doubt, pointing out that 12-word phrases encode only 128 bits of security compared to the robust 256 bits of their 24-word counterparts.
One responder noted, "It is extremely safe. Regardless if you use 12, 15, 18, 21, or 24 words, the resulting private key is still 256 bits," raising questions about the actual differences between these lengths.
Technical Insights on Seed Phrase Length
The consensus remains mixed. Commenters emphasize the importance of using secure hardware wallets for generating seed phrases. A user pointed out, "I would not use something that’s not bip39 for future proofing and reusability," highlighting that compatibility with standards is crucial for ongoing efficacy.
Furthermore, a fascinating perspective emerged regarding quantum computing's potential risks. One individual asked, "Intuitively I want to believe 24 would be more difficult for quantum computers to crack than a 12-word phrase, is that actually true?" This concern echoes the ongoing conversation about future threats to cryptocurrency security.
Key Points and Sentiments
Here's a summary of the key takeaways from the recent discussions:
✅ Security Claims: Users debate the effectiveness of 12-word phrases, with some presenting solid arguments for their safety.
